7 * Provides functionality for mapping between
8 * LCID and Posix IDs or ICU locale to codepage
9 *
10 * Note: All classes and code in this file are
11 * intended for internal use only.
12 *
13 * Methods of interest:
14 * unsigned long convertToLCID(const char*);
15 * const char* convertToPosix(unsigned long);
16 *
17 * Kathleen Wilson, 4/30/96
18 *
19 * Date Name Description
20 * 3/11/97 aliu Fixed off-by-one bug in assignment operator. Added
21 * setId() method and safety check against
22 * MAX_ID_LENGTH.
23 * 04/23/99 stephen Added C wrapper for convertToPosix.
24 * 09/18/00 george Removed the memory leaks.
25 * 08/23/01 george Convert to C
