21 * CP949 is EUC-KR, extended with UHC (Unified Hangul Code).
23 * Some variants of CP949 (in JDK, Windows-2000, ICU) also add:
25 * 2. Private area mappings:
28 * 0xC9{A1..FE} U+E000..U+E05D
29 * 0xFE{A1..FE} U+E05E..U+E0BB
31 * We add them too because, although there are backward compatibility problems
32 * when a character from a private area is moved to an official Unicode code
33 * point, they are useful for some people in practice.
