Thanks again for your help.
I did not expect that method to be the issue as it seemed stable
throughout the development process.

I am now using iconv( "utf-8", "ascii//TRANSLIT", $filename ); as the
first step in the cleaning process. This solved the issue instantly.

Thanks again and kind regards
