/*
* Implementation notes:
*
* (1)"Standard based" (ASCII, JIS_X_0201 and JIS_X_0208) ISO2022-JP charset
* is provided by the base implementation of this class.
*
* Three Microsoft ISO2022-JP variants, MS50220, MS50221 and MSISO2022JP
* are provided via subclasses.
*
* (2)MS50220 and MS50221 are assumed to work the same way as Microsoft
* CP50220 and CP50221's 7-bit implementation works by using CP5022X
* specific JIS0208 and JIS0212 mapping tables (generated via Microsoft's
* MultiByteToWideChar/WideCharToMultiByte APIs). The only difference
* between these 2 classes is that MS50220 does not support singlebyte
* halfwidth kana (Uff61-Uff9f) shiftin mechanism when "encoding", instead
* these halfwidth kana characters are converted to their fullwidth JIS0208
* counterparts.
*
* The difference between the standard JIS_X_0208 and JIS_X_0212 mappings
* and the CP50220/50221 specific are
*
* 0208 mapping:
* 1)0x213d <-> U2015 (compared to U2014)
* 2)One way mappings for 5 characters below
* u2225 (ms) -> 0x2142 <-> u2016 (jis)
* uff0d (ms) -> 0x215d <-> u2212 (jis)
* uffe0 (ms) -> 0x2171 <-> u00a2 (jis)
* uffe1 (ms) -> 0x2172 <-> u00a3 (jis)
* uffe2 (ms) -> 0x224c <-> u00ac (jis)
* //should consider 0xff5e -> 0x2141 <-> U301c?
* 3)NEC Row13 0x2d21-0x2d79
* 4)85-94 ku <-> UE000,UE3AB (includes NEC selected
* IBM kanji in 89-92ku)
* 5)UFF61-UFF9f -> Fullwidth 0208 KANA
*
* 0212 mapping:
* 1)0x2237 <-> UFF5E (Fullwidth Tilde)
* 2)0x2271 <-> U2116 (Numero Sign)
* 3)85-94 ku <-> UE3AC - UE757
*
* (3)MSISO2022JP uses a JIS0208 mapping generated from MS932DB.b2c
* and MS932DB.c2b by converting the SJIS codepoints back to their
* JIS0208 counterparts. With the exception of
*
* (a)Codepoints with a resulting JIS0208 codepoints beyond 0x7e00 are
* dropped (this includs the IBM Extended Kanji/Non-kanji from 0x9321
* to 0x972c)
* (b)The Unicode codepoints that the IBM Extended Kanji/Non-kanji are
* mapped to (in MS932) are mapped back to NEC selected IBM Kanji/
* Non-kanji area at 0x7921-0x7c7e.
*
* Compared to JIS_X_0208 mapping, this MS932 based mapping has
* (a)different mappings for 7 JIS codepoints
* 0x213d <-> U2015
* 0x2141 <-> UFF5E
* 0x2142 <-> U2225
* 0x215d <-> Uff0d
* 0x2171 <-> Uffe0
* 0x2172 <-> Uffe1
* 0x224c <-> Uffe2
* (b)added one-way c2b mappings for
* U00b8 -> 0x2124
* U00b7 -> 0x2126
* U00af -> 0x2131
* U00ab -> 0x2263
* U00bb -> 0x2264
* U3094 -> 0x2574
* U00b5 -> 0x264c
* (c)NEC Row 13
* (d)NEC selected IBM extended Kanji/Non-kanji
* These codepoints are mapped to the same Unicode codepoints as
* the MS932 does, while MS50220/50221 maps them to the Unicode
* private area.
*
* # There is also an interesting difference when compared to MS5022X
* 0208 mapping for JIS codepoint "0x2D60", MS932 maps it to U301d
* but MS5022X maps it to U301e, obvious MS5022X is wrong, but...
