Dear Bug Team!
When opening a text file containing the words "méi wéi Europäësch
Compétitivitéit" (Luxembourgish for "more than European
Competitivity"), the text appears garbled in some strange Chinese
character set (Zh/Big5). When opening the same text in vi, it appears
normal. As I'm typing this in emacs, I'm not sure how this will arrive
at the other end...
I admit that the Chinese might overtake Europe one day, but IMHO emacs
is way ahead of its time here ;-)
Is there a possibility to de-activate these political forecasts? ;-)
Thanks,
Alain

Either set the LANG variable or use `set-language-environment'. If
your environment is LANG=C or LANG=POSIX (the default), XEmacs uses a
rather random set of preferences for guessing encodings.
If your LANG variable _is_ set to something sane (such as
de_DE.ISO8859-15----just an example, sorry, but I don't know how to
spell "Luxembourg Luxembourgish" in ISO 639/3166), please try
killing the buffer with the garbled text, M-x set-language-environment
RET TAB to get a list of known environments, pick one as close to what
you want as possible, and try finding the file again.
Either way, please tell us your LANG (or LC_ALL or LC_CTYPE if you're
a locale guru) values and the language environment so we can improve
this for future versions.
If your LANG variable is not set or is set to some other language/
encoding than the one normal for Luxembourgish, and setting it
properly and restarting XEmacs doesn't fix things, please let us know
what you set it to, and what the inappropriate result is.

Hi Alain,
I had the same problem and believe I found the correct cause and an
acceptable solution -- at least what I describe below works for me
since a long time.
I assume your file is in some encoding like ISO-8859-1? (If it is
UTF-8, I can't explain this behaviour.)
You may already have noticed that the problem goes away if the file
does not contain consecutive occurrences of characters outside ASCII,
that is, no words like "Europäësch"?
First the solution: In the file "src/mule-coding.c", near the end
of the function "iso2022_detect", replace the clause
else if (data->odd_high_byte_groups > 0 &&
data->even_high_byte_groups > 0)
SET_DET_RESULTS (st, iso2022, DET_SOMEWHAT_UNLIKELY);
with
else if (data->odd_high_byte_groups > 0 &&
data->even_high_byte_groups > 0)
{
SET_DET_RESULTS (st, iso2022, DET_SOMEWHAT_UNLIKELY);
if (data->odd_high_byte_groups >= 2 * data->even_high_byte_groups)
DET_RESULT (st, iso_8_1) = DET_SOMEWHAT_LIKELY;
}
and recompile XEmacs.
Second, the explanation: This part of XEmacs is responsible for a kind
of statistical recognition of file encodings. To do so among other things
it counts the number of occurrences of runs of even and odd lengths of
bytes >= 0xA0 in the first few KB of the file.
If the file is encoded in something like ISO-8859-1 most such runs will
be one byte long (e.g. "Compétitivitéit" contains two such runs), but
sometimes there will be some of length two, too, e.g. in "Europäësch".
If both occur, the clause above will trigger and erroneously reduce the
likelihood of encodings like ISO-8859-1 below the default level, leaving
Zh/Big5 as the most likely encoding.
The changed version above simply checks that the relative frequency
of occurrence of runs of even and odd lengths is compatible with the
assumption that the language/encoding in question uses bytes >= 0xA0
mostly singly, but sometimes in pairs, and increases the likelihood of
encodings like ISO-8859-1 in this case.
Hope this helps
Yours
