Question

I’ve a PHP script and MYSQL database.
In this database, I’ve a lot of entries, in French, English, Chinese, Russian, …
I would like a php function to return true, if the $var contains other characters of latin (so, russian, chinese, …)
Euro, Dollars, and specials characters should’nt return false, but true.

I’ve tried with iconv, mb_check_encoding, but no way, the russian (and other) is converted to : “????????”

Could you help ?
Thanks

I had to do something similar for work, and (with help) came up with this:

<?php
function other_chars($str){
    $american = preg_match("/^[\p{Latin}\p{Nd}\p{Common}]*$/u", $str);
    if(!$american){
        return true;
    }
    return false;
}
