/*
 *  5 types of entry in SJIS_X_0213/Unicode mapping table
 *
 *  (1)Single-Byte
 *     JIS_X_0213 does not define single-byte character itself, the
 *     JIS_X_0201 entries are added in for sjis implementation.
 *
 *  (2)Double-Byte SJIS <-> BMP Unicode
 *     ex: 0x8140 U+3000    # IDEOGRAPHIC SPACE
 *
 *  (3)Double-Byte SJIS <-> Supplementary
 *     ex: 0xFCF0 U+2A61A   # <cjk> [2000] [Unicode3.1]
 *
 *  (4)Double-Byte SJIS <-> Composite
 *   ex: 0x83F6 U+31F7+309A # [2000]
 *
 *  (5)"Windows-only" special mapping entries
