Wide-Latin bash script?

Is there any script, preferably bash or Perl, that will convert normal ASCII ("deal") into wide-width latin ("ｄｅａｌ")?

Thanks.

something like this?


if ($_SERVER['argc'] == 1) {
    echo "usage: php asc2wwl.php [ascii string]\n";
    exit();
}

echo ascii_to_wwlatin($_SERVER['argv'][1]);
