+/*
+* 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...
