You miss multibyte string functions on your server
http://us3.php.net/manual/en/book.mbstring.php. Multibyte string functions are
important if you use any special characters in your content. Non-multibyte-aware
string functions could be used instead as workaround, but only if no special
characters are used.

E.g. with multibyte string function
$teil=mb_substr("abcüde",2,3); // outputs cüd
$teil=mb_substr("abcüde",2,2); // outputs cü

With non-multibyte functions

$teil=substr("abcüde",2,3); // outputs cü instead of cüd, fails to detect the
ending of the multibyte character
$teil=substr("abcüde",2,2); // outputs corrupted garbage string because of  the
2-Byte character ü being cutted in the middle

I would not recommend to use this module without multibyte functions installed
on the server at all.

But I will add error handling to prevent the error output.
