Lol, this is a sweet.
But please don't count my answer as "Enrico is an encoding specialist".

Lex, thanks for spending time and efforts to track this issue down and
all the debugging which was involved. Actually much appreciated even if
otherwise not explicitly said. This is also true for the rest of the
gang taking care of the geany-users mailing list in the last
weeks/months. Yeah.

I think the only real problem is that we get an encoding from the
locale which doesn't match one of our predefined strings (at the top of
src/encodings.c). And this is the only point we should fix, so that the
further code relying on the index of the mentioned mapping keeps

Some quick ideas to find a solution for the problem:

- try to define whether this is a Windows-only problem or whether it
might happen on non-Windows systems as well
- we should review the way we retrieve the locale name from the system,
for Windows in particular
- try to create an additional mapping of possible other locale names
which can be directly mapped to the known ones known by Geany*

* there is a file charset.alias or something with a similar name used
by iconv, IIRC. And this file holds a mapping of alias names for
encodings resp. charsets. I don't remember the details right now but on
Windows it would be especially easy to distribute such an additional
mapping. Though I still need to find some useful documentation on that
and howto do it properly.
