Here are all the best (official and most commonly accepted) character set names (labels/identifiers) to use in your XML declaration encoding or HTML content-type charset, plus the aliases, Windows code pages and descriptive titles.

The most complete charset name reference

Looking around the Internet I could not find a comprehensive character set name reference so I combined several online resources into this one. The primary reference for web technologies like XML is the IANA list of character sets but it:

  • does not have some widely referenced charsets such as the Mac charsets
  • only specifies best encoding name "preferred MIME name" in a few cases
  • does not provide descriptive title names such as "Central European (ISO)"
  • does not give corresponding Windows code pages
  • duplicates aliases for different charsets (e.g. csISO)
  • should not have ASMO-708 "Arabic (ASMO 708)" as an alias of iso-8859-6 "Arabic (ISO)"
  • should have Latin5 as ISO-8859-9 (Turkish) not ISO-8859-5 (Cyrillic)
  • should not have euc-kr as an alias of KS_C_5601-1987 when it is its own charset
  • It might be reasonable to list duplicate and ambiguous aliases if someone is trying to interpret the intention of an obscure alias in their data, but here I chose to remove all duplicates. I also made some choices (which will remain controversial) as follows:

  • euc-jp is code page 20932 and not 51932
  • iso-2022-jp is code page 50220 and not 50221 or 50222
  • code page 50222 is only named _iso-2022-jp$sio
  • Also, where the Windows code page was available I have used it as a basis for associating aliases that identify the same charset. Hopefully this has not led to grouping any unequal charsets together.

    Notes

    Everyone is encouraged to use Unicode (especially UTF-8), however the reality is that many of these non-Unicode encodings are in broad use and we still need to standardize the way we identify them.

    I will be posting the full XML data set for this list and my firstobject XML editor foal script that built it at a later time.
