Re: Gettext Mac GUI application returning wrong characters

I cannot reproduce this with a sample program (attached) that writes some text
to a file. Whether started from the 'Terminal' or from the 'Finder', the text
that it writes to the file is in German, with umlaut.

> $ locale
> LANG=""
> LC_COLLATE="C"
> LC_CTYPE="UTF-8"
> LC_MESSAGES="C"
> LC_MONETARY="C"
> LC_NUMERIC="C"
> LC_TIME="C"
> LC_ALL=

This is normal. The 'Terminal' does not reflect the language preferences
through environment variables. libintl uses the CoreFoundation API to get
the language preferences.

Can you please adapt the attached test case in a way that reproduces the
behaviour you are seeing? Or otherwise provide a simple test case that
I could try?

If you can't do that, it would be good if you could print the values of
  getenv ("LANG")
  getenv ("LC_CTYPE")
  getenv ("LC_ALL")
  getenv ("OUTPUT_CHARSET")
from your program.
