Take care when you try to strip whitespaces out of an UTF-8 text. Using something like:
<?php
$text = preg_replace( "{\s+}", ' ', $text );
?>
brokes in my case the letter à which is hex c3a0. But a0 is a whitespace. So use
<?php
$text = preg_replace( "{[ \t]+}", ' ', $text );
?>
to strip all spaces and tabs, or better, use a multibyte function like mb_ereg_replace.
