Non-ascii characters caused problems with SVN function and were replaced

Non-ascii characters caused problems with SVN function and were replaced
with a ? by SourceForge.net in your original log message, which follows:

Certain characters in translations would mess up on the post, such as an
umlaut would appear as ö in html, but after being posted it appears as
? so matching would always fail, making it impossible for those with
chars like that to mod/delete servers. (Bug #742705)
