1.12 +// Last Update: September 7, 1999
1.13 +// Revision History:
1.14 +// 09/07/1999 - initial version.
1.15 +// 09/28/1999 - changed leftbyte and rightbyte from char to unsigned char
1.16 +// in struct DByte
1.17 +// 04/10/1999 - changed leftbyte. rightbyte to uint8_t in struct DByte;
1.18 +// added table UnicodeToGBKTable[0x5200]
1.19 +//
1.20 +// 05/16/2000 - added gUnicodeToGBKTableInitialized flag for optimization
1.21 +// ======================================================================================
1.22 +// Table GBKToUnicode[] maps the GBK code to its unicode.
1.23 +// The mapping data of this GBK table is obtained from
1.24 +// ftp://ftp.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP936.TXT
1.25 +// Frank Tang of Netscape wrote the original perl tool to re-align the
1.26 +// mapping data into an 8-item per line format ( i.e. file cp936map.txt ).
1.27 +//
1.28 +// The valid GBK charset range: left byte is [0x81, 0xfe], right byte are
1.29 +// [0x40, 0x7e] and [0x80, 0xfe]. But for the convenience of index
1.30 +// calculation, the table here has a single consecutive range of
1.31 +// [0x40, 0xfe] for the right byte. Those invalid chars whose right byte
1.32 +// is 0x7f will be mapped to undefined unicode 0xFFFF.
1.33 +//
1.34 +//
1.35 +// Table UnicodeToGBK[] maps the unicode to GBK code. To reduce memory usage, we
1.36 +// only do Unicode to GBK table mapping for unicode between 0x4E00 and 0xA000;
1.37 +// Others let converter to do search from table GBKToUnicode[]. If we want further
1.38 +// trade memory for performance, we can let more unicode to do table mapping to get
1.39 +// its GBK instead of searching table GBKToUnicode[].
