[Moin-user] error when installing packages with attachments that contain special characters in their name

[R.Bauer]

Hi

I tried a similiar example on my linux system with LC_ALL=de_DE.utf8
This matches the encoding on the server.

I created a file jülich.txt with vim.
There is no problem to create a package and install it later on back
with that name used.

I guess you have a non utf-8 encoding in your file names. You can check
by converting such a filename to the utf-8 encoding by convmv (convmv -
converts filenames from one encoding to another). May be your filenames
have ISO-8859-1.

The fix is then to convert all old filenames to the yet used encoding of
utf-8 on all modern OS.

cheers
Reimar
