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. - */ - -#include "isoir165ext.h" - -static int -isoir165_mbtowc (conv_t conv, ucs4_t *pwc, const unsigned char *s, int n) -{ - int ret; - - /* Map full-width pinyin (row 0x28) like half-width pinyin (row 0x2B). */ - if (s[0] == 0x28) { - if (n >= 2) { - unsigned char c2 = s[1]; - if (c2 >= 0x21 && c2 <= 0x40) { - unsigned char buf[2]; - buf[0] = 0x2b; - buf[1] = c2; - ret = isoir165ext_mbtowc(conv,pwc,buf,2); - if (ret != RET_ILSEQ) - return ret; - } - } - } - /* Try the GB2312 -> Unicode table. */ - ret = gb2312_mbtowc(conv,pwc,s,n); - if (ret != RET_ILSEQ) - return ret; - /* Row 0x2A is GB_1988-80. */ - if (s[0] == 0x2a) { - if (n >= 2) { - unsigned char c2 = s[1]; - if (c2 >= 0x21 && c2 < 0x7f) { - int ret = iso646_cn_mbtowc(conv,pwc,s+1,1); - if (ret != 1) abort(); - return 2; - } - return RET_ILSEQ; - } - return RET_TOOFEW(0); - } - /* Try the ISO-IR-165 extensions -> Unicode table. */ - ret = isoir165ext_mbtowc(conv,pwc,s,n); - return ret; -} - -static int -isoir165_wctomb (conv_t conv, unsigned char *r, ucs4_t wc, int n) -{ - unsigned char buf[1]; - int ret; - - /* Try the Unicode -> GB2312 table table. */ - ret = gb2312_wctomb(conv,r,wc,n); - if (ret != RET_ILUNI) { - if (ret != 2) abort(); - if (!(r[0] == 0x28 && r[1] >= 0x21 && r[1] <= 0x40)) - return ret; - } - /* Row 0x2A is GB_1988-80. */ - ret = iso646_cn_wctomb(conv,buf,wc,1); - if (ret != RET_ILUNI) { - if (ret != 1) abort(); - if (buf[0] >= 0x21 && buf[0] < 0x7f) { - if (n >= 2) { - r[0] = 0x2a; - r[1] = buf[0]; - return 2; - } - return RET_TOOSMALL; - } - } - /* Try the Unicode -> ISO-IR-165 extensions table. */ - ret = isoir165ext_wctomb(conv,r,wc,n); - return ret; -} -- cgit v1.2.3
