-/*
- * ISO-IR-165 is an extension of GB 2312, consisting of:
- * 1. GB 6345.1-86 corrections:
- * Two corrections to GB 2312, at 0x2367 and 0x6F71.
- * 2. GB 6345.1-86 additions:
- * - 6 new full-width pinyin characters in row 0x28.
- * - ISO646-CN in row 0x2A.
- * - 32 half-width pinyin characters in row 0x2B.
- * 3. GB 8565.2-88 additions:
- * - 50 characters in row 0x2D.
- * - 92 characters in row 0x2E.
- * - 93 characters in row 0x2F.
- * - 470 characters in rows 0x7A-0x7E.
- * 4. ISO-IR-165 additions:
- * - 22 characters in row 0x26.
- * - 94 characters in row 0x2C.
- * - 44 new characters in row 0x2D.
- * - 1 new character in row 0x2F.
- *
- * The conversion table was created from the following sources:
- * Ad 1. The 0x2367 correction is already integrated in the unicode.org
- * GB2312.TXT table. The 0x6F71 mapping is the same in the unicode.org
- * GB2312.TXT and UNIHAN.TXT table and in Koichi Yasuoka's Uni2GB table,
- * so we assume it's correct.
- * The unicode.org UNIHAN.TXT table about GB 8565 is not usable: it has
- * extraneous code points at rows 0x28, 0x2C, 0x2D. Note also that it does
- * not list the 69 non-hanzi in row 0x2F. Moreover, it has the characters
- * 0x2F7A-0x2F7D shifted down by one to 0x2F79-0x2F7C.
- * Therefore we take the GB8565 and ISO-IR-165 data from Koichi Yasuoka's
- * Uni2GB table.
- * Ad 1. Yasuoka maps 0x2367 to U+0261 (small script g) and 0x2840 to U+FF47
- * (full-width small normal g). While coherent with ISO-IR's 165.pdf,
- * this disagrees with Ken Lunde's book: He says that ISO-IR-165
- * includes the GB6345 correction, i.e. maps 0x2367 to U+FF47 or U+0067
- * and _not_ to U+0261 (small script g).
- * To overcome the confusion, we just map both 0x2367 and 0x2840 to
- * U+FF47.
- * Ad 2. Row 0x28: Add a mapping from 0x283F to U+01F9.
- * Row 0x2A: Mapping is well-known, also present in Koichi Yasuoka's
- * table.
- * Row 0x2B: Typed in by hand from appendix E in Ken Lunde's book.
- * When converting from Unicode to ISO-IR-165, prefer the half-width
- * range 0x2B{21..40} to the full-width range 0x28{21..40}.
- * Ad 3. Rows 0x2D, 0x2E: Both Koichi Yasuoka's Uni2GB table and the UNIHAN.TXT
- * data for GB 8565 agree here.
- * Row 0x2F: Taken from Koichi Yasuoka's Uni2GB table.
- * Rows 0x7A-0x7E: Koichi Yasuoka's Uni2GB table and the UNIHAN.TXT
- * data for GB 8565 agree here mostly. Differences:
- * 0x7C38 -> U+6F26 or U+527A ? We choose U+6F26.
- * 0x7C5A -> U+7A40 or U+6996 ? We choose U+6996.
- * Ad 4. Row 0x26: Mapping unknown.
- * Rows 0x2C, 0x2D: Both Koichi Yasuoka's Uni2GB table and the UNIHAN.TXT
- * data for GB 8565 (!) agree here.
- * Row 0x2F: Taken from Koichi Yasuoka's Uni2GB table.
