+    //              Has several variations in 1978, 1983, 1990 and 1997.
+    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
+    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
+    //              2 planes, first is superset of 0208, second - revised 0212.
+    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
+
+    // Byte encodings are:
+    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
+    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
+    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
+    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
+    //               0x00-0x7F       - lower part of 0201

+    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
+    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
+    //               Used as-is in ISO2022 family.
+    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
+    //                0201-1976 Roman, 0208-1978, 0208-1983.
+    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
+    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
+    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.

+    //  * Windows CP 951: Microsoft variant of Big5-HKSCS-2001. Seems to be never public. http://me.abelcheung.org/articles/research/what-is-cp951/
+    //  * Big5-2003 (Taiwan standard) almost superset of cp950.
+    //  * Unicode-at-on (UAO) / Mozilla 1.8. Falling out of use on the Web. Not supported by other browsers.
+    //  * Big5-HKSCS (-2001, -2004, -2008). Hong Kong standard. 
+    //    many unicode code points moved from PUA to Supplementary plane (U+2XXXX) over the years.
+    //    Plus, it has 4 combining sequences.
+    //    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
+    //    because big5-hkscs is the only encoding to include astral characters in non-algorithmic way.
+    //    Implementations are not consistent within browsers; sometimes labeled as just big5.
+    //    MS Internet Explorer switches from big5 to big5-hkscs when a patch applied.
+    //    Great discussion & recap of what's going on https://bugzilla.mozilla.org/show_bug.cgi?id=912470#c31
