UTF-8 and M-x shell?

UTF-8 and M-x shell?

[Daniel Pfeiffer]

Hi,

I'm migrating my Gnu/Linux to LANG=de_DE.UTF-8 and finding that I need to
recode my old Latin-9 filenames.

But now Gnu Emacs (2-3 weeks old CVS) M-x shell gets problems.  First off, the
buffer still comes up in Latin-1.  That can apparently be fixed with
(set-language-environment "utf-8"), but only interactively, not in .emacs.el! 
But it doesn't help:

- M-! umlaut-emitting-command displays old (1-byte) umlauts as octal and utf-8
correctly

- but with the same commands in the shell buffer, with mode-line u:, it still
displays everything as one-byte.

What must I do for M-x shell to respect $LANG, like an xterm?

(Btw. before I had LANG=de_DE@euro, which is Latin-9, but Emacs wrongly
defaulted to Latin-1 -- which luckily is quite similar.)

best regards
Daniel

Strange.  What happens if you put (set-language-environment "utf-8")
into ~/.emacs?  Is there an error message?

That's how it is supposed to be.

What does M-x describe-coding-system RET RET say when in the shell
buffer?  The codings for process i/o should be utf-8.  As a
workaround, you could try M-: (set-process-coding-system nil 'utf-8
'utf-8) RET from the *shell* buffer.

That's also strange -- my Emacs defaulted to Latin-9 when I did this.
Maybe it was a font problem?  I had set "Emacs.font:
yadda-yadda-iso8859-15" originally, but had to revert to "Emacs.font:
yadda-yadda-iso8859-1" to get the right behavior.

Sorry to all!

I had two sins: I set up latin-1 explicitly -- presumably from ancient times
when this didn't work automatically -- after my new utf-8 setup which proved
unnecessary, and I associated ctext (whatever that may have been good for)
with shell.

Ich Danke Dir Kai!

I suggest to post this to emacs-pretest-bug@gnu.org, since you are
talking about the CVS version of Emacs.
