Looks to me as though that system is defaulting to a strange or
incorrect locale.  As a result, it's treating non-ASCII characters
as being non-alphanumeric, so PmWiki's MakePageName() function thinks
they are punctuation and removes them.

Try adding

   setlocale(LC_ALL, 'de_DE');

to your local/config.php and see if that resolves the problem.  

I also notice (via ?action=phpinfo) that this site is running a fairly
old version of PHP (4.1.2) and PCRE (3.4, 22-Aug-2000).  It's
possible that PHP on this site isn't properly recognizing the 
POSIX character classes such as [:alnum:], [:alpha:], [:digit:], etc.
