Re: OS X and umlauts in file names

Hi Thomas,

Thanks for the feed-back. I know the problem from SVN, too, but I had the
hope, that Git was smarter than SVN for this topic. IIRC, one could get SVN
working "somehow" with umlauts on OS X by setting some environment variable.
Unfortunately, I don't remember the details any more.

Basically, getting it "somehow" to work on OS X is just one minor step. IMHO
Git should standardize on file names in the repository and do the
platform-specific conversion independent of any locale setting, if needed.
Then and only then it would be possible to get the same characters out of
the repository, no matter whether the file was added or checked out on OS X,
Linux or Windows.

At the moment we've got a problem report regarding our SmartGit GUI client:
the user says, on command line it[1] works (German OS X) but not with
SmartGit, for me it doesn't even work on the command line (English OS X). As
you may know, Java uses characters for file names, the Java runtime
internally converts from the platform-specific byte-representation on disk
to characters. I can't simply tunnel the file name as byte array to the
invoked Git command - I simply don't know how to transform the characters of
the file name to a representation the Git command line client will
understand[2].

Tom

[1] e.g. to stage or commit files with umlauts in the file name
[2] executing an external command in Java also "only" works with strings
(aka characters), not with byte sequences

I'm on an English OS X 10.6.2 and I created a sample file with umlauts in
its name (Überlänge.txt). When I try to stage the file in the terminal, I
can't complete the file name by typing the Ü and hitting the tab key, but I
can complete it by typing an U and hitting the tab key. Unfortunately, after
executing

 git stage Überlänge.txt

This is because of OS X's unicode normalisation.  Try any of the
many threads on the topic, e.g.,

  http://thread.gmane.org/gmane.comp.version-control.git/70688

The short version is that this Ü is in fact decomposed into an
U-umlaut duo.

Considering that this leads to endless fun[*] not just with git, and
that we German speakers have an easy way out (Ueberlaenge), I can only
suggest that you avoid umlauts wherever possible to preserve
the sanity of your users.

Übungen.  Took me a while to figure out what was going on.
