Git doesn't care. Just use the *same* sequence everywhere. Make sure
something doesn't change it. Because if something changes it, git will
track it.
The problem is that you don't control the sequence that everybody uses.
See this example:
melo@speed(~)$ uname -a

EDT 2007 i686 i686 i386 GNU/Linux

LANG=en_US.UTF-8

So two (simulated in this test) users who use different LANG settings
will be in trouble in no time.
What I take from this conversation is that I have to specify, for
each project I work on, which encoding we should use, across all
users, before they start using git with files with accented chars.
The difference I see between us is that if I tell my filesystem that
I want to name my file with a particular string encoded in X, users
using encoding Y will be able to read it correctly. I like my
filesystem to make that work for me.
Best regards,
