Error bunzip2ing files with non-ASCI-names

Error bunzip2ing files with non-ASCI-names

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

On my GNU/Linux (SuSE 9.3) workstation emacs is unable to bunzip2
files whose names are not ASCII, maybe because file names are utf-8 encoded on
this system.

Steps to reproduce this bug:
In the shell:
  > echo xx > bä.txt     # the second letter of the filename is a-Umlaut
  > bzip2 bä.txt 
  > emacs -q --no-site-file
In emacs
- type "M-x auto-compression-mode"
- open a dired buffer which contains the file (the filename is displayed
  correctly with the Umlaut), 
- move point to the file and press enter
The error message "File exists, but cannot be read" is displayed 
and an empty buffer is created. If I rename the file with dired-do-rename to
'bae.txt.bz2', the file can be opened without any problems.
bunzip2 has no problems to unzip the file with its original name (tests started
from eshell, xterm, text-only terminal)
The same happens if I use gzip instead of bzip2.

Files which are not compressed can be read without problems, even if their names
contain non-ASCII characters. Uncompressing the file 'bä.txt.bz2' in a dired
buffer with 'Z' (dired-do-compress) works, too, and gives the readable file
'bä.txt'.

What happens if you visit bä.txt with `C-x C-f' instead of via Dired?

I assumed you mean open bä.txt.bz2 with `C-x C-f'; this gives the same
behaviour (error message and empty buffer). bä.txt can be opened in any
way I can think of without problems

Sorry, that is what I meant.  This problem was just fixed today in CVS
(Emacs 22):
