The function is not by me.

/**

function utf8_wordwrap($str, $width, $break=" ", $cut = false){
if(!$cut){
$regexp = '#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){'.$width.',}\b#U';
} else {
$regexp = '#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){'.$width.'}#';
}
if(function_exists('mb_strlen')){
$str_len = mb_strlen($str, 'UTF-8');
} else {
$str_len = preg_match_all('/[\x00-\x7F\xC0-\xFD]/', $str, $var_empty);
}
$while_what = ceil($str_len / $width);
$i = 1;
$return = '';
while ($i < $while_what){
if (!preg_match($regexp, $str, $matches)) {
break;
}
$string = $matches[0];
$return .= $string . $break;
$str = substr($str,strlen($string));
$i++;
}
return $return.$str;
}
