Comment (by p_enrique):

 The current patch uses `preg_replace()` with the `u`-modifier without
 checking if the PCRE UTF-8 extension is active. This will throw warnings
 and blanks the string. There should be a check for the extension and a
 fallback to plain UTF-8 bytes. And since we're using the UTF-8 extension,
 we can use the Unicode character properties for filtering. See attached
 patch.
