iso-8859-8/windows-1255 (Hebrew) and iso-8859-9/windows-1254 (Turkish)

iso-8859-8/windows-1255 (Hebrew) and iso-8859-9/windows-1254 (Turkish)

[Reiner Steib]

Hi,

I've learned that windows-1254 is a superset of iso-8859-9 (Turkish)
and windows-1255 is a superset of iso-8859-8 (Hebrew).

So it would probably make sense to add these pairs to
`mm-charset-synonym-alist' and `mm-charset-override-alist' as well, in
the same way we do for iso-8859-1/windows-1252 (West Europe), see the
patch below.  In western Europe, articles are often mislabeled as
iso-8859-1, when in fact the article is windows-1252.

Does anyone (especially people using those charsets) see a problem
with this change?
