How do I remove accents from characters in a PHP string without relying on the default

How do I remove accents from characters in a PHP string?

When using iconv, the server's correct implementation determines the success of accent removal.

The default "glibc" implementation is incompatible, with a more suitable option being "libiconv".

If unable to recompile PHP with the correct implementation, consider using the following code:

function remove_accents($string) {
    if ( !preg_match('/[\x80-\xff]/', $string) )
        return $string;

    $chars = array(
    // Decompositions for Latin-1 Supplement
    chr(195).chr(128) => 'A', chr(195).chr(129) => 'A',
    chr(195).chr(130) => 'A', chr(195).chr(131) => 'A',
    chr(195).chr(132) => 'A', chr(195).chr(133) => 'A',
    chr(195).chr(135) => 'C', chr(195).chr(136) => 'E',
