Definitely not in my copy of GNU Emacs 22.0.50:

Having in .emacs

        (set-language-environment       'German)

*scratch*, *Messages*, *mail*, dired buffers ... have a modeline starting with


which does not stand for ISO 8859-15. '0' stands stands for ISO 8859-15. And relying on LC_CTYPE or LANG, as usual, I get utf-8 encoded buffers, just as I wish and prefer.

When I first used this statement I thought that GNU Emacs would set a few things 'right,' and prefer German man pages, too, or messages/ tool tips/comand output/holidays/calendar would come in German. It took a long time for me to understand that this particular statement was resetting what I had prepared with shell environment variables.

Could be set-language-environment is an obsolete function now that GNU Emacs understands LC_ALL or LANG ...
