function strtr_utf8($str, $from, $to) {
    $keys = array();
    $values = array();
    preg_match_all('/./u', $from, $keys);
    preg_match_all('/./u', $to, $values);
    $mapping = array_combine($keys[0], $values[0]);
    return strtr($str, $mapping);
}

You should consider that the second parameter can also be an array for mapping. – Gumbo Sep 21 '09 at 13:14
I didn't need that, but it would be more faithful to strtr's signature. – joeforker Sep 21 '09 at 13:29

    function strtr_utf8($str, $from, $to)
    {
        $keys = array();
        $values = array();
        if(!is_array($from))
        {
            preg_match_all('/./u', $from, $keys);
            preg_match_all('/./u', $to, $values);
            $mapping = array_combine($keys[0], $values[0]);
        }else
            $mapping=$from;
        return strtr($str, $mapping);
    }

I slightly edited the joeforker's function to return back the functionality of using second parameter as array for replace_pairs.

It works great. The accepted answer should be moved to this one. — Jose Gómez, Oct 08 '15 at 04:00
