Your hosting account's libraries aren't recognizing Ü as being a letter.
Such information is normally stored in the "locale" libraries in the
OS; but if the hosting provider doesn't bother to supply them,
then PHP doesn't think of accented characters as being letters
(or know how to do case conversions, or a number of other things).

Try explicitly setting a locale in local/config.php.  For example,
for German try one of:

    setlocale(LC_ALL, 'de_DE');
    setlocale(LC_ALL, 'german');
    setlocale(LC_ALL, 'de');

The pmwiki.org site essentially does the equivalent of

    setlocale(LC_ALL, 'en_US');

(the en_US locale on my systems does understand the Latin-1 alphabet).

If none of those work, you may be stuck, unless you can get the
hosting provider to make the locale libraries available.

Or, you may need to switch to using a UTF-8 character set.  UTF-8 
doesn't really know how to recognize letters either, so WikiWords 
won't work, but at least PmWiki has workarounds in place for 
supporting UTF-8 characters in page names.
