1. Summarise the issue (what were doing, what went wrong?)

ben@sarun[1]: ~/tmp > cd bla 
ben@sarun[1]: .../tmp/bla > darcs initialize   
ben@sarun[1]: .../tmp/bla > darcs tag öü
ben@sarun[1]: .../tmp/bla > echo $LC_CTYPE 
de_DE.UTF-8
ben@sarun[1]: .../tmp/bla > darcs changes -a

2. What behaviour were you expecting instead?

I expected that darcs displays

ben@sarun[1]: .../tmp/bla > darcs changes -a
Wed Oct 24 20:55:35 CEST 2012  Ben Franksen <ben.franksen@online.de>
  tagged öü

that is, takes $LC_CTYPE into account when displaying patch meta-data.

I *dearly hope* that darcs internally stores the meta-data in locale
independent format and uses the current locale to interpret the user's
input when recording a patch, but I have not verified that. (If not,
this would be another issue and a much graver one).

3. What darcs version are you using? (Try: darcs --exact-version)

2.9.5 (+ 157 patches)

This is fixed in darcs 2.14, on Linux, right?

On the other hand it's still broken on Windows so I'm inclined to re-
open it to track that problem, or I could open a new one.

Yes, it is fixed on Linux. You opened another ticket for the Windows
issues you observed after that. I made some comments there IIRC.

I meant the comments I made here: http://bugs.darcs.net/patch1628

OK, I'm marking it as resolved, as it is on Linux.

I've raised issue2590 and issue2591 to cover the two aspects of the 
problems on Windows (the issue described in this ticket isn't fixed, 
and other tests have regressed), and will disable the relevant tests 
for now with pointers to those issues.
