Yes. It's LANG=de_DE.UTF-8. It's valid in Mac OS X.

I did not succeed to make my *shell* buffers display the u: in the  
mode-line. The best I can achieve is *scratch* or *Help* with ``u:´´  
and this in .emacs (although it might not be necessary, because  
without this modification *shell* seems to behave the same):

         (modify-coding-system-alist 'process "\\*shell\\*\\'"   'utf-8)

This file was not installed from the Fink package. Strings does not  
reveal such a string in the GNU ls binary, only /sw/share/locale,  
where the localised messages are located.


I've also tried to set ``(modify-coding-system-alist 'process "\\*.*  
output\\*\\'" 'iso-8859-15-unix)´´ (usual TeX is at an 8bit level) to  
make AUCTeX output readable. The modifications for both get recorded  
in process-coding-system-alist, but they do not seem to effect more.  
One thing *is* true: UTF-8 output from commands in *shell* is  
correctly presented. I cannot say it's a bug, or two, so I stay with it.
