 Unicode 6.3 update
 http://www.unicode.org/review/pri249/  -- beta review
 http://www.unicode.org/reports/uax-proposed-updates.html
 http://www.unicode.org/versions/beta-6.3.0.html#notable_issues
 http://www.unicode.org/reports/tr44/tr44-11.html
 *** ICU Trac
 - ticket 10128: update ICU to Unicode 6.3 beta
 - ticket 10168: update ICU to Unicode 6.3 final
 - C++ branches/markus/uni63 at r33552 from trunk at r33551
 - Java branches/markus/uni63 at r33550 from trunk at r33553
 - ticket 10142: implement Unicode 6.3 bidi algorithm additions
 *** Unicode version numbers
 - makedata.mak
 - uchar.h
   (configure.in & configure: have been modified to extract the version from uchar.h)
 - com.ibm.icu.util.VersionInfo
 - com.ibm.icu.dev.test.lang.UCharacterTest.VERSION_
 - Run ICU4C "configure" _after_ updating the Unicode version number in uchar.h
   so that the makefiles see the new version number.
 *** data files & enums & parser code
 * file preparation
 - download UCD, UCA & IDNA files
 - make sure that the Unicode data folder passed into preparseucd.py
   includes a copy of the latest IdnaMappingTable.txt (can be in some subfolder)
 - modify preparseucd.py:
   parse new file BidiBrackets.txt
   with new properties bpb=Bidi_Paired_Bracket and bpt=Bidi_Paired_Bracket_Type
 - ~/svn.icutools/trunk/src/unicode$ py/preparseucd.py ~/unidata/uni63/20130425 ~/svn.icu/uni63/src ~/svn.icutools/trunk/src
 - This writes files (especially ppucd.txt) to the ICU4C unidata and testdata subfolders.
 - Check test file diffs for previously commented-out, known-failing data lines;
   probably need to keep those commented out.
 * PropertyAliases.txt changes
 - 1 new Enumerated Property
   bpt                      ; Bidi_Paired_Bracket_Type
   -> uchar.h & UProperty.java & UCharacter.BidiPairedBracketType
   -> ubidi_props.h & .c & UBiDiProps.java
   -> remember to write the max value at UBIDI_MAX_VALUES_INDEX
   -> uprops.cpp
   -> change ubidi.icu format version from 2.0 to 2.1
 - 1 new Miscellaneous Property
   bpb                      ; Bidi_Paired_Bracket
   -> uchar.h & UProperty.java
   -> ppucd.h & .cpp
 * PropertyValueAliases.txt changes
 - 3 Bidi_Paired_Bracket_Type (bpt) values:
   bpt; c                                ; Close
   bpt; n                                ; None
   bpt; o                                ; Open
   -> uchar.h & UCharacter.BidiPairedBracketType
   -> ubidi_props.h & .c & UBiDiProps.java
   -> change ubidi.icu format version from 2.0 to 2.1
 - 4 new Bidi_Class (bc) values:
   bc ; FSI                              ; First_Strong_Isolate
   bc ; LRI                              ; Left_To_Right_Isolate
   bc ; RLI                              ; Right_To_Left_Isolate
   bc ; PDI                              ; Pop_Directional_Isolate
   -> uchar.h & UCharacterEnums.ECharacterDirection
   -> until the bidi code gets updated,
      Roozbeh suggests mapping the new bc values to ON (Other_Neutral)
 - 3 new Word_Break (WB) values:
   WB ; HL                               ; Hebrew_Letter
   WB ; SQ                               ; Single_Quote
   WB ; DQ                               ; Double_Quote
   -> uchar.h & UCharacter.WordBreak
   -> first time Word_Break numeric constants exceed 4 bits (now 17 values)
 - 2 new script codes from ISO 15924 http://www.unicode.org/iso15924/codechanges.html
   (added 2012-10-16)
   Aghb  239     Caucasian Albanian
   Mahj  314     Mahajani
   -> uscript.h
   -> com.ibm.icu.lang.UScript
     find     USCRIPT_([^ ]+) *= ([0-9]+),(.+)
     replace  public static final int \1 = \2;\3
   -> preparseucd.py _scripts_only_in_iso15924
   -> add to expectedLong and expectedShort names in cintltst/cucdapi.c/TestUScriptCodeAPI()
       and in com.ibm.icu.dev.test.lang.TestUScript.java
   -> update Script metadata: SCRIPT_PROPS[] in uscript_props.cpp & UScript.ScriptMetadata
      (not strictly necessary for NOT_ENCODED scripts)

 - rebuild ICU (make install) & tools
 - run genuca again (see step above) so that it picks up the new case mappings and nfc.nrm
 - rebuild ICU (make install) & tools
 * update uts46test.cpp and UTS46Test.java if there are new characters that are equivalent to
   sequences with non-LDH ASCII (that is, their decompositions contain '=' or similar)
 - grep IdnaMappingTable.txt or uts46.txt for "disallowed_STD3_valid" on non-ASCII characters
 - Unicode 6.0..6.3: U+2260, U+226E, U+226F
 - nothing new in 6.3, no test file to update
 * update Java data files
 - refresh just the UCD-related files, just to be safe

 * refresh Java test .txt files
 - copy new .txt files into ICU4J's main/tests/core/src/com/ibm/icu/dev/data/unicode
 * UCA -- mostly skipped for ICU 52 / Unicode 6.3, except update coll/* files
 - get output from Mark's tools; look in http://www.unicode.org/Public/UCA/<beta version>/
 - CLDR root files for ICU are in CollationAuxiliary.zip; unpack that
 - update source/data/unidata/FractionalUCA.txt with FractionalUCA_SHORT.txt
 - update source/data/unidata/UCARules.txt with UCA_Rules_SHORT.txt
   (note removing the underscore before "Rules")
 - update (ICU4C)/source/test/testdata/CollationTest_*.txt
   and (ICU4J)/main/tests/collate/src/com/ibm/icu/dev/data/CollationTest_*.txt
   with output from Mark's Unicode tools (..._CLDR_..._SHORT.txt)
 - check test file diffs for previously commented-out, known-failing data lines;
   probably need to keep those commented out
 - check FractionalUCA.txt for manual changes of lead bytes from IMPLICIT to Hani
 - run genuca, see command line above
 - rebuild ICU4C
 - refresh ICU4J collation data:
   (subset of instructions above for properties data refresh, except copies all coll/*)
     ~/svn.icu/uni63/dbg$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install
     ~/svn.icu/uni63/dbg$ mkdir -p /tmp/icu4j/com/ibm/icu/impl/data/icudt52b/coll

 - run all tests with the *_SHORT.txt or the full files (the full ones have comments, useful for debugging)
 - note on intltest: if collate/UCAConformanceTest fails, then
   utility/MultithreadTest/TestCollators will fail as well;
   fix the conformance test before looking into the multi-thread test
 * test ICU, fix test code where necessary
 * When refreshing all of ICU4J data from ICU4C
 - ~/svn.icu/uni63/dbg$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install
 - cp /tmp/icu4j/main/shared/data/icudata.jar ~/svn.icu4j/trunk/src/main/shared/data
 or
 - ~/svn.icu/uni63/dbg$ make ICU4J_ROOT=~/svn.icu4j/trunk/src icu4j-data-install
 *** LayoutEngine script information
 - skipped for Unicode 6.3: no new scripts
 *** merge the Unicode update branches back onto the trunk
 - do not merge the icudata.jar and testdata.jar,
   instead rebuild them from merged & tested ICU4C

 - uchar.h
   (configure.in & configure: have been modified to extract the version from uchar.h)
 - com.ibm.icu.util.VersionInfo
 - com.ibm.icu.dev.test.lang.UCharacterTest.VERSION_
 *** data files & enums & parser code
 * file preparation
 - download UCD, UCA & IDNA files
 - make sure that the Unicode data folder passed into preparseucd.py
   includes a copy of the latest IdnaMappingTable.txt (can be in some subfolder)
 - modify preparseucd.py: NamesList.txt is now in UTF-8
 - ~/svn.icu/tools/trunk/src/unicode$ py/preparseucd.py ~/uni62/20120816 ~/svn.icu/uni62/src ~/svn.icu/tools/trunk/src
 - This writes files (especially ppucd.txt) to the ICU4C unidata and testdata subfolders.
 - Check test file diffs for previously commented-out, known-failing data lines;
   probably need to keep those commented out.
 * PropertyValueAliases.txt changes
 - 1 new Line_Break (lb) value:
   lb ; RI                               ; Regional_Indicator
   -> uchar.h & UCharacter.LineBreak
 - 1 new Word_Break (WB) value:
   WB ; RI                               ; Regional_Indicator
   -> uchar.h & UCharacter.WordBreak
 - 1 new Grapheme_Cluster_Break (GCB) value:
   GCB; RI                               ; Regional_Indicator
   -> uchar.h & UCharacter.GraphemeClusterBreak
 * 3 new numeric values
   The new value -1, which was really supposed to be NaN but that would have required
   new UnicodeData.txt syntax, can already be represented as a "fraction" of -1/1,
   but encodeNumericValue() in corepropsbuilder.cpp had to be fixed.
     cp;12456;na=CUNEIFORM NUMERIC SIGN NIGIDAMIN;nv=-1
     cp;12457;na=CUNEIFORM NUMERIC SIGN NIGIDAESH;nv=-1
   The two new values 216000 and 432000 require an addition to the encoding of numeric values.
     cp;12432;na=CUNEIFORM NUMERIC SIGN SHAR2 TIMES GAL PLUS DISH;nv=216000
     cp;12433;na=CUNEIFORM NUMERIC SIGN SHAR2 TIMES GAL PLUS MIN;nv=432000
   -> uprops.h, uchar.c & UCharacterProperty.java
   -> cucdtst.c & UCharacterTest.java

 Future Unicode update
 Tools simplified since the Unicode 6.1 update. See
 - http://site.icu-project.org/design/props/ppucd
 - http://bugs.icu-project.org/trac/wiki/Markus/ReviewTicket8972
 * Unicode version numbers
 - icutools/unicode/makedefs.sh was deleted, so one fewer place for version & path updates
 * file preparation
 - ucdcopy.py, idna2nrm.py and genpname/preparse.pl replaced by preparseucd.py:
 - ~/svn.icu/tools/trunk/src/unicode$ py/preparseucd.py ~/uni61/20120118 ~/svn.icu/trunk/src ~/svn.icu/tools/trunk/src
 - This writes files (especially ppucd.txt) to the ICU4C unidata and testdata subfolders.
 - Check test file diffs for previously commented-out, known-failing data lines;
   probably need to keep those commented out.
 * PropertyValueAliases.txt changes
 - Script codes that are in ISO 15924 but not in Unicode are now listed in
   preparseucd.py, in the _scripts_only_in_iso15924 variable.
   If there are new ISO codes, then add them.
   If Unicode adds some of them, then remove them from the .py variable.
 * UnicodeData.txt changes
 - No more manual changes for CJK ranges for algorithmic names;
   those are now written to ppucd.txt and genprops reads them from there.
 * generate core properties data files (makeprops.sh was deleted)
 - ~/svn.icu/tools/trunk/dbg/unicode$ c/genprops/genprops ~/svn.icu/trunk/src
 * no more manual updates of source/data/unidata/norm2/nfkc_cf.txt
 - it is now generated by preparseucd.py
 * no more separate idna2nrm.py run and manual copying to generate source/data/unidata/norm2/uts46.txt
 - it is now generated by preparseucd.py
 - make sure that the Unicode data folder passed into preparseucd.py
   includes a copy of http://www.unicode.org/Public/idna/6.1.0/IdnaMappingTable.txt
   (can be in some subfolder)
 * generate normalization data files
 - ~/svn.icu/trunk/dbg$ export LD_LIBRARY_PATH=~/svn.icu/trunk/dbg/lib
 - ~/svn.icu/trunk/dbg$ SRC_DATA_IN=~/svn.icu/trunk/src/source/data/in

     e.g. the ICU version in this path: BLD_DATA_FILES=$ICU_BLD/data/out/build/icudt49l
 *** data files & enums & parser code
 * file preparation
 ~/svn.icu/tools/trunk/src/unicode/c/genprops/misc$ ./ucdcopy.py ~/uni61/20111205/ucd ~/uni61/processed
 - This prepares both unidata and testdata files in respective output subfolders.
 - Check test file diffs for previously commented-out, known-failing data lines;
   probably need to keep those commented out.

 - 2 new Line_Break (lb) values:
   CJ=Conditional_Japanese_Starter
   HL=Hebrew_Letter

     find     USCRIPT_([^ ]+) *= ([0-9]+),(.+)
     replace  public static final int \1 = \2;\3

   -> add to expectedLong and expectedShort names in cintltst/cucdapi.c/TestUScriptCodeAPI()
       and in com.ibm.icu.dev.test.lang.TestUScript.java
 * UnicodeData.txt changes
 - the last Unihan code point changes from U+9FCB to U+9FCC
   search for both 9FCB (end) and 9FCC (limit) (regex 9FC[BC], case-insensitive)
   + do change gennames.c
   + do change swapCJK() in ucol.cpp & ImplicitCEGenerator.java
 * DerivedBidiClass.txt changes
 - 2 new default-AL blocks:
 #     Arabic Extended-A: U+08A0  -  U+08FF  (was default-R)
 #     Arabic Mathematical Alphabetic Symbols:
 #                       U+1EE00  - U+1EEFF  (was default-R)
 - 2 new default-R blocks:
 #     Meroitic Hieroglyphs:
 #                        U+10980 - U+1099F
 #     Meroitic Cursive:  U+109A0 - U+109FF
   -> should be picked up by the explicit data in the file
 * NameAliases.txt changes
 - from
     # Each line has two fields
     # First field: Code point
     # Second field: Alias
 - to
     # Each line has three fields, as described here:
     #
     # First field:  Code point
     # Second field: Alias
     # Third field:  Type
 - Also, the file previously allowed multiple aliases but only now does it
   actually provide multiple, even multiple of the same type. For example,
     FEFF;BYTE ORDER MARK;alternate
     FEFF;BOM;abbreviation
     FEFF;ZWNBSP;abbreviation
 - This breaks our gennames parser, unames.icu data structure, and API.
   Fix gennames to only pick up "correction" aliases.
   New ticket #8963 for further changes.
 * run genpname/preparse.pl (on Linux)
   + cd ~/svn.icu/tools/trunk/src/unicode/c/genpname

 * build ICU (make install)
   so that the tools build can pick up the new definitions from the installed header files.

 * update uts46test.cpp and UTS46Test.java if there are new characters that are equivalent to
   sequences with non-LDH ASCII (that is, their decompositions contain '=' or similar)
 - grep IdnaMappingTable.txt or uts46.txt for "disallowed_STD3_valid" on non-ASCII characters
 - Unicode 6.0..6.1: U+2260, U+226E, U+226F
 - nothing new in 6.1, no test file to update
 * generate core properties data files
 - in initial bootstrapping, change the UCA version
   in source/data/unidata/FractionalUCA.txt to match the new Unicode version

   + if genrb fails to build coll/root.res with an U_INVALID_FORMAT_ERROR,
     check if the UCA version in FractionalUCA.txt matches the new Unicode version
     (see step above)
 - run makeuca.sh so that genuca picks up the new case mappings and nfc.nrm:
   ~/svn.icu/tools/trunk/src/unicode$ ./makeuca.sh ~/svn.icu/trunk/src ~/svn.icu/trunk/bld

 * refresh Java test .txt files
 - copy new .txt files into ICU4J's main/tests/core/src/com/ibm/icu/dev/data/unicode
 * un-hardcode normalization skippable (NF*_Inert) test data
 - removes one manual step from the Unicode upgrade, and removes dependency on one of Mark's tools
 * copy updated break iterator test files
 - now handled by early ucdcopy.py and
   copying the uni60/processed/testdata files to ~/svn.icu/trunk/src/source/test/testdata
   (old instructions:
    copy from (Unicode 6.0)/ucd/auxiliary/*BreakTest-6....txt
    to ~/svn.icu/trunk/src/source/test/testdata)
 - they are not used in ICU4J
 * UCA

     http://www.unicode.org/Public/UCA/6.0.0/
     http://www.unicode.org/~mdavis/uca/
 - update source/data/unidata/FractionalUCA.txt with FractionalUCA_SHORT.txt
 - update source/data/unidata/UCARules.txt with UCA_Rules_SHORT.txt
 - update Han-implicit ranges for new CJK extensions:
   swapCJK() in ucol.cpp & ImplicitCEGenerator.java
 - genuca: allow bytes 02 for U+FFFE, new merge-sort character;
   do not add it into invuca so that tailoring primary-after an ignorable works
 - genuca: permit space between [variable top] bytes
 - ucol.cpp: treat noncharacters like unassigned rather than ignorable
 - run makeuca.sh:
   ~/svn.icu/tools/trunk/src/unicode$ ./makeuca.sh ~/svn.icu/trunk/src ~/svn.icu/trunk/bld
 - rebuild ICU4C
 - refresh ICU4J collation data:
   (subset of instructions above for properties data refresh, except copies all coll/*)
     ~/svn.icu/trunk/bld$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install

   and (ICU4J)/main/tests/collate/src/com/ibm/icu/dev/data/CollationTest_*.txt
   with output from Mark's Unicode tools
 - run all tests with the *_SHORT.txt or the full files (the full ones have comments)
 - note on intltest: if collate/UCAConformanceTest fails, then
   utility/MultithreadTest/TestCollators will fail as well;
   fix the conformance test before looking into the multi-thread test
 * When refreshing all of ICU4J data from ICU4C
 - ~/svn.icu/trunk/bld$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install
 - cp /tmp/icu4j/main/shared/data/icudata.jar ~/svn.icu4j/trunk/src/main/shared/data
 or
 - ~/svn.icu/trunk/bld$ make ICU4J_ROOT=~/svn.icu4j/trunk/src icu4j-data-install
 *** LayoutEngine script information
 (For details see the Unicode 5.2 change log below.)
 * Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguages.h,
 ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (It also generates
 ScriptRunData.cpp, which is no longer needed.)
 The generated files have a current copyright date and "@draft" statement.
 * copy the above files into <icu>/source/layout, replacing the old files.
 * fix mixed line endings
 * review the diffs and fix incorrect @draft and missing aliases;
   Unicode-derived script codes should be "born stable" like constants in uchar.h, uscript.h etc.
 * manually re-add the "Indic script xyz v.2" tags in ScriptAndLanguageTags.h

     ->
     sc ; Zinh      ; Inherited                        ; Qaai
   new Line_Break (lb) value:

   new Joining_Group (jg) values: Farsi_Yeh, Nya
   other new values:
     ccc; 214; ATA  ; Attached_Above
 - DerivedBidiClass.txt
   new default-R range: U+1E800 - U+1EFFF
 - UnicodeData.txt
   all of the ISO comments are gone
   new CJK block end:

   new CJK block:
 A700;<CJK Ideograph Extension C, First>;Lo;0;L;;;;;N;;;;;
 B734;<CJK Ideograph Extension C, Last>;Lo;0;L;;;;;N;;;;;
 * genpname
 - run preparse.pl
   + cd \svn\icuproj\icu\trunk\source\tools\genpname
   + make sure that data.h is writable
   + perl preparse.pl \svn\icuproj\icu\trunk > out.txt
   + preparse.pl complains with errors like the following:
       Error: sc:Egyp already set to Egyptian_Hieroglyphs, cannot set to Egyp at preparse.pl line 1322, <GEN6> line 34.
     This is because ICU 4.0 had scripts from ISO 15924 which are now
     added to Unicode 5.2, and the Perl script shows a conflict between SyntheticPropertyValueAliases.txt
     and PropertyValueAliases.txt.
     -> Removed duplicate script entries from SyntheticPropertyValueAliases.txt:
        Egyp, Java, Lana, Mtei, Orkh, Armi, Avst, Kthi, Phli, Prti, Samr, Tavt
   + preparse.pl complains with errors about block names missing from uchar.h; add them
 * uchar.h & uscript.h & uprops.h & uprops.c & genprops
 - new block & script values
   + 26 new blocks
     copy new blocks from Blocks.txt
     MS VC++ 2008 regular expression:
       find "^{[0-9A-F]+}\.\.{[0-9A-F]+}; {[A-Z].+}$"
       replace with "    UBLOCK_\3 = 172, /*[\1]*/"
   + several new script values already added in ICU 4.0 for ISO 15924 coverage
     (removed from SyntheticPropertyValueAliases.txt, see genpname notes above)
   + 3 new script values added for ISO 15924 and Unicode 5.2 coverage
   + 1 new script value added for ISO 15924 coverage (not in Unicode 5.2)
     (added to SyntheticPropertyValueAliases.txt)
 - new Joining Group (JG) values: Farsi_Yeh, Nya
 - new Line_Break (lb) value:
     lb ; CP        ; Close_Parenthesis
 * hardcoded Unihan range end/limit
 - Unihan range end moves from 9FC3 to 9FCB
   search for both 9FC3 (end) and 9FC4 (limit) (regex 9FC[34], case-insensitive)
   + do change gennames.c
 * Compare definitions of new binary properties with what we used to use
   in algorithms, to see if the definitions changed.
 - Verified that definitions for Cased and Case_Ignorable are unchanged.
   The gencase tool now parses the newly public Case_Ignorable values
   in case the definition changes in the future.
 * uchar.c & uprops.h & uprops.c & genprops
 - new numeric values that didn't exist in Unicode data before:
 /7, 1/9, 1/10, 3/10, 1/16, 3/16
   the ones with denominators >9 cannot be supported by uprops.icu formatVersion 5,
   therefore redesign the encoding of numeric types and values for formatVersion 6;
   design for simple numbers up to at least 144 ("one gross"),
   large values up to at least 10^20,
   and fractions with numerators -1..17 and denominators 1..16
   to cover current and expected future values
   (e.g., more Han numeric values, Meroitic twelfths)
 * reimplement Hangul_Syllable_Type for new Jamo characters
 - the old code assumed that all Jamo characters are in the 11xx block
 - Unicode 5.2 fills holes there and adds new Jamo characters in
     A960..A97F; Hangul Jamo Extended-A
   and in
     D7B0..D7FF; Hangul Jamo Extended-B
 - Hangul_Syllable_Type can be trivially derived from a subset of
   Grapheme_Cluster_Break values
 * build Unicode data source code for hardcoding core data

 - run all tests with the *_SHORT.txt or the full files (the full ones have comments)
   not just the *_STUB.txt files
 - note on intltest: if collate/UCAConformanceTest fails, then
   utility/MultithreadTest/TestCollators will fail as well;
   fix the conformance test before looking into the multi-thread test
 *** Implement Cased & Case_Ignorable properties
 - via UProperty; call ucase.h functions ucase_getType() and ucase_getTypeOrIgnorable()
 - Problem: These properties should be disjoint, but aren't
 - UTC 2009nov decision: skip all Case_Ignorable regardless of whether they are Cased or not
 - change ucase.icu to be able to store any combination of Cased and Case_Ignorable
 *** Implement Changes_When_Xyz properties
 - without stored data
 *** Implement Name_Alias property
 - add it as another name field in unames.icu
 - make it available via u_charName() and UCharNameChoice and
 - consider it in u_charFromName()
 *** Break iterators
 * Update break iterator rules to new UAX versions and new property values
 * Update source/test/testdata/<boundary>Test.txt files from <unicode.org ucd>/ucd/auxiliary
 *** new BidiTest file
 - review format and data
 - copy BidiTest.txt to source/test/testdata
 - write test code using this data
 - fix ICU code where it fails the conformance test
 *** Java
 - generally, find and update code corresponding to C/C++
 - UCharacter.UnicodeBlock constants:
   a) add an _ID integer per new block, update COUNT
   b) add a class instance per new block
      Visual Studio regex:
         find            UBLOCK_{[^ ]+} = [0-9]+, {/.+}
         replace with    public static final UnicodeBlock \1 = new UnicodeBlock("\1", \1_ID); \2
 - CHAR_NAME_ALIAS -> UCharacter.getNameAlias() and getCharFromNameAlias()
 - port test changes to Java
 *** LayoutEngine script information
 (For comparison, see the Unicode 5.1 update: http://bugs.icu-project.org/trac/changeset/23833)
 * Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguages.h,
 ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (It also generates
 ScriptRunData.cpp, which is no longer needed.)
 The generated files have a current copyright date and "@draft" statement.
 -> Eric Mader wrote in email on 20090930:
     "I think the tool has been modified to update @draft to @stable for
      older scripts and to add @draft for new scripts.
      (I worked with an intern on this last year.)
      You should check the output after you run it."
 * copy the above files into <icu>/source/layout, replacing the old files.
 * fix mixed line endings
 * review the diffs and fix incorrect @draft and missing aliases
 * manually re-add the "Indic script xyz v.2" tags in ScriptAndLanguageTags.h
 Add new default entries to the indicClassTables array in <icu>/source/layout/IndicClassTables.cpp
 and the complexTable array in <icu>/source/layoutex/ParagraphLayout.cpp. (This step should be automated...)
 -> Eric Mader wrote in email on 20090930:
     "This is just a matter of making sure that all the per-script tables have
      entries for any new scripts that were added.
      If any new Indic characters were added, then the class tables in
      IndicClassTables.cpp should be updated to reflect this.
      John Emmons should know how to do this if it's required."

   + cd \svn\icuproj\icu\uni51\source\tools\genpname
   + make sure that data.h is writable
   + perl preparse.pl \svn\icuproj\icu\uni51 > out.txt
   + preparse.pl complains with errors like the following:
       Error: sc:Cari already set to Carian, cannot set to Cari at preparse.pl line 1308, <GEN6> line 30.
     This is because ICU 3.8 had scripts from ISO 15924 which are now
     added to Unicode 5.1, and the script shows a conflict between SyntheticPropertyValueAliases.txt
     and PropertyValueAliases.txt.
     -> Removed duplicate script entries from SyntheticPropertyValueAliases.txt:
        Cari, Cham, Kali, Lepc, Lyci, Lydi, Olck, Rjng, Saur, Sund, Vaii
   + PropertyValueAliases.txt now explicitly contains values for boolean properties:
       N/Y, No/Yes, F/T, False/True
     -> Added N/No and Y/Yes to preparse.pl function read_PropertyValueAliases.
        It will use further values from the file if present.
 * uchar.h & uscript.h & uprops.h & uprops.c & genprops
 - new block & script values
   + 17 new blocks
   + 11 new script values already added in ICU 3.8 for ISO 15924 coverage
     (removed from SyntheticPropertyValueAliases.txt)
   + 14 new script values added for ISO 15924 coverage (not in Unicode 5.1)
     (added to SyntheticPropertyValueAliases.txt)
 - uprops.icu (uprops.h) only provides 7 bits for script codes.
   In ICU 4.0 there are USCRIPT_CODE_LIMIT=130 script codes now.
   There is none above 127 yet which is the script code for an
   assigned Unicode character, so ICU 4.0 uprops.icu does not store any
   script code values greater than 127.
   However, it does need to store the maximum script value=USCRIPT_CODE_LIMIT-1=129
   in a parallel bit field, and that overflows now.
   Also, future values >=128 would be incompatible anyway.
   uprops.h is modified to move around several of the bit fields
   in the properties vector words, and now uses 8 bits for the script code.
   Two other bit fields also grow to accommodate future growth:
   Block (current count: 172) grows from 8 to 9 bits,
   and Word_Break grows from 4 to 5 bits.
 - renamed property Simple_Case_Folding (sfc->scf)
   + nothing to be done: handled as normal alias

 * Further changes in the 2008-02-29 update:
 - Default_Ignorable_Code_Point: The new file removes Cc, Cs, noncharacters from DICP
   because they should not normally be invisible.
 - new Joining Group (JG) value Burushashki_Yeh_Barree was renamed to Burushaski_Yeh_Barree (one 'h' removed)
 - new Grapheme_Cluster_Break (GCB) value: PP=Prepend
 - new Word_Break (WB) value: NL=Newline
 * hardcoded Unihan range end/limit (see Unicode 4.1 update for comparison)
 - Unihan range end moves from 9FBB to 9FC3
   search for both 9FBB (end) and 9FBC (limit) (regex 9FB[BC], case-insensitive)
