Answer 1

str_replace() should be able to handle Unicode characters If it does not, you are probably not passing it Unicode.

Make sure that you are handling Unicode strings all the way through from the displayed website to the PHP script. See this article for further information: „Unicode-friendly PHP and MySQL“.

Answer 2

I have used http://www.php.net/preg_replace on similar cases.

$replace = array(
   '/ä/u'=>'a',
   '/p/u'=>'r',
);

$patterns = array_keys($replace);
$replacements = array_values($replace);

echo preg_replace($patterns, $replacements, $string);
