  6. // == Japanese/ShiftJIS ====================================================
  7. // All japanese encodings are based on JIS X set of standards:
  8. // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
  9. // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes.
  10. // Has several variations in 1978, 1983, 1990 and 1997.
  11. // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
  12. // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
  13. // 2 planes, first is superset of 0208, second - revised 0212.
  14. // Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
  15. // Byte encodings are:
  16. // * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
  17. // encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
  18. // Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
  19. // * EUC-JP: Up to 3 bytes per character. Used mostly on *nixes.
  20. // 0x00-0x7F - lower part of 0201
  21. // 0x8E, 0xA1-0xDF - upper part of 0201
  22. // (0xA1-0xFE)x2 - 0208 plane (94x94).
  23. // 0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
  24. // * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
  25. // Used as-is in ISO2022 family.
  26. // * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII,
  27. // 0201-1976 Roman, 0208-1978, 0208-1983.
  28. // * ISO2022-JP-1: Adds esc seq for 0212-1990.
  29. // * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
  30. // * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
  31. // * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
  32. //
  33. // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.
  34. //
  35. // Overall, it seems that it's a mess :( http://www8.plala.or.jp/tkubota1/unicode-symbols-map2.html

  119. // * Windows CP 950: Microsoft variant of Big5. Canonical: http://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP950.TXT
  120. // * Windows CP 951: Microsoft variant of Big5-HKSCS-2001. Seems to be never public. http://me.abelcheung.org/articles/research/what-is-cp951/
  121. // * Big5-2003 (Taiwan standard) almost superset of cp950.
  122. // * Unicode-at-on (UAO) / Mozilla 1.8. Falling out of use on the Web. Not supported by other browsers.
  123. // * Big5-HKSCS (-2001, -2004, -2008). Hong Kong standard.
  124. // many unicode code points moved from PUA to Supplementary plane (U+2XXXX) over the years.
  125. // Plus, it has 4 combining sequences.
  126. // Seems that Mozilla refused to support it for 10 yrs. https://bugzilla.mozilla.org/show_bug.cgi?id=162431 https://bugzilla.mozilla.org/show_bug.cgi?id=310299
  127. // because big5-hkscs is the only encoding to include astral characters in non-algorithmic way.
  128. // Implementations are not consistent within browsers; sometimes labeled as just big5.
  129. // MS Internet Explorer switches from big5 to big5-hkscs when a patch applied.
  130. // Great discussion & recap of what's going on https://bugzilla.mozilla.org/show_bug.cgi?id=912470#c31
  131. // In the encoder, it might make sense to support encoding old PUA mappings to Big5 bytes seq-s.
