  It's not very consistent. For instance, there are entries like
fr_FR.ISO-8859-1, es_ES.ISO-8859-1 in addition to fr_FR.ISO_8859-1,
fr_FR.iso88591, en_ES.iso88591, en_ES.ISO_8859-1.  while fr_CA.ISO-8859-1
is not there. As for EUC-KR and EUC-JP, ja_JP.EUC-JP along with
ja_JP.(eucJP|EUC|EUC_JP) is there, but ko_KR.EUC-KR is not present
although there are  other variants of ko_KR.EUC-KR
ko_KR.(EUC|euckr|euc|eucKR)

  How about preparing a patch and submitting it to fixes@xfree86.org? 
It doesn't take long :-)

  glibc maintainers seem to want to standardize on preferred
MIME names for existing encodings such as ISO-8859-1, EUC-JP, EUC-KR
and UTF-8. Therefore, perhaps it's not a bad idea to make them
available across all locales in X locale.alias ?
