A few of the trials I have done:
1.- following your advice I have switched the settings, in the bash_profile
to "fr_CA.utf8", in my .emacs I have set
(prefer-coding-system 'utf-8)
Here is a part of the emacs' help for showing the coding system.
Priority order for recognizing coding systems when reading files:
1. mule-utf-8 (alias: utf-8)
2. iso-latin-1 (alias: iso-8859-1 latin-1)
3. mule-utf-16be-with-signature (alias: utf-16be-with-signature
mule-utf-16-be utf-16-be)
...
In emacs' dired I see french accents correctly used. The R-help buffer is
garbled???
2.- In the bash_profile I set the languages "LC_.." variables to "fr_CA",
same setting in .emacs then the R-help buffer is fine BUT in dired french
accents are replaced by "\351" for "é" for example and I can't open any
files, from dired, where there is an accent in the date by pressing "f" or
"<enter>", emacs tells me the file doesn't exist anymore.
3.- "fr_CA" in the bash_profile and emacs' defaults in .emacs; then
everything is fine BUT utf-8 is not the first order priority to recognize
coding systems.
Priority order for recognizing coding systems when reading files:
1. iso-latin-1 (alias: iso-8859-1 latin-1)
2. mule-utf-8 (alias: utf-8)
3. mule-utf-16be-with-signature (alias: utf-16be-with-signature
mule-utf-16-be utf-16-be)
...
4.- I also have tried flavors of "en_US.utf8", and without the "utf8" with
similar results??
Don't know what to do with this any more?
Thanks again for your support Martin, it is highly appreciated,
