JapaneseDetector.h A Japanese legacy encoding detector for detecting between Shift_JIS, EUC-JP, and, optionally, ISO-2022-JP _given_ the assumption that the encoding is one of those. # Principle of Operation The detector is based on two observations: 1. The ISO-2022-JP escape sequences don't normally occur in Shift_JIS or EUC-JP, so encountering such an escape sequence (before non-ASCII has been encountered) can be taken as indication of ISO-2022-JP. 2. When normal (full-with) kana or common kanji encoded as Shift_JIS is decoded as EUC-JP, or vice versa, the result is either an error or half-width katakana, and it's very uncommon for Japanese HTML to have half-width katakana character before a normal kana or common kanji character. Therefore, if decoding as Shift_JIS results in error or have-width katakana, the detector decides that the content is EUC-JP, and vice versa. # Failure Modes The detector gives the wrong answer if the text has a half-width katakana character before normal kana or common kanji. Some uncommon kanji are undecidable. (All JIS X 0208 Level 1 kanji are decidable.) The half-width katakana issue is mainly relevant for old 8-bit JIS X 0201-only text files that would decode correctly as Shift_JIS but that the detector detects as EUC-JP. The undecidable kanji issue does not realistically show up when a full document is fed to the detector, because, realistically, in a full document, there is at least one kana or common kanji. It can occur, though, if the detector is only run on a prefix of a document and the prefix only contains the title of the document. It is possible for document title to consist entirely of undecidable kanji. (Indeed, Japanese Wikipedia has articles with such titles.) If the detector is undecided, a fallback to Shift_JIS should be used. 4997
