Something broke non-ASCII characters on popot.org's mod pages.
Compare
the comments here with
an archived version.
It also affects
the title of this mod (and a few other mods), compare
an archived version.
Mod titles on user profiles are affected as well.
In both cases, the non-ASCII characters are replaced with HTML named entities, with the bytes interpreted in the Windows-1252 encoding.
If you are using
htmlentities then you should either specify the correct encoding (UTF-8), or use
htmlspecialchars instead, which only replaces some ASCII characters.
Non-ASCII characters in
mods.xml are broken in the same way, except here there are no HTML entities in the source.
