Comment 1 for bug 102935

Just some observations under MacOSX with a custom bash and coreutils (to get at least some UTF-8 support in there ;-))

zerok@akira:~/tmp/test$ bzr diff
=== removed file '\xc3\xa6\xc3\xb8\xc3\x9c\xc3\x89'
---------------------------------------------------------------------

The difference in the filenames (removed vs. unknown) is not visible in the terminal. There both look like the first one.

hg somehow manages the same situation and also seems to stay workable on a more or less similarly configured Linux box.

(Note: galaxy had version 0.9.3 of hg (with python 2.4.4) running while this test was conducted, akira was on hg 0.9.4 with python 2.5.1)

At least when I look at this output it seems like hg is uniformly expanding the characters (similar to what the coreutils do) while bzr operates on two different names.

I hope this is useful.
