Bug report

I compared encodings.aliases with the IANA registry (see https://www.iana.org/assignments/character-sets/character-sets.xhtml, I used the CSV format) and found more missing aliases. Most of them are with the "cs" prefix, but there were also CCSID01140, iso-ir-149, KS_C_5601-1989 (we only have KS_C_5601-1987), GB_2312-80, windows-936, etc. One alias, csHPRoman8, was not normalized, so it did not work.

There are some errors in the IANA registry. ISO-8859-11 is an alias of TIS-620, while in Python they differ by one character (euro). MS_Kanji is an alias of Shift_JIS, while in Python it is an alias of cp932 (not IANA registered). I suppose Python is more correct here.
