Accent string cutting

Question

Possible duplicate:
Trim a multibyte string by n characters

Hello,

I am developing a site in French and I created a function that cuts the string after X number of characters. It works great, but when the last character has an accent, he has a symbol (?), Not a symbol.

Here is my function

function neat_trim3($str, $n, $delim='...') {
    $len = strlen($str);
    if ($len > $n) {
        $tocut = $len-$n;
        $output = substr($str,0,-$tocut);
        return $len.' - '.$output.$delim;
    }
    else {
        return $str;
    }
}

Example

$str = "C'est une soirée privé ce soir";
echo eat_trim3($str, 15 , '...' );   
// GIVES ME             C'est une soir ...

The rest of the page fine-tunes the page, I can even repeat the same line without a cut, and it works fine.

Any help was appreciated.

Thank.
