ok, i prepared a function for this:

/**
 * Convert ascii to upper/lower case for use of independet locale 
conversion.
 *
 * @param string  Input string
 * @param string  kind of conversion, use 'upper' or 'lower'
 */
function asciiToCase($string,$case) {
    $lchars='abcdefghijklmnopqrstuvwxyz';
    $uchars='ABCDEFGHIJKLMNOPQRSTUVWXYZ';
 return $case=='upper' ? strtr($string,$lchars,$uchars) : 
strtr($string,$uchars,$lchars);
}
