Put the character into the regular expression - no special handling needed.

If you want to show me some data in context I'll show you how it might work.

Ahh, thought I had an example... Sure enough!
<?php // RAY_temp_array007.php
echo "<pre>";

// SET WESTERN CHARACTER SET - SEE http://dev.w3.org/html5/markup/meta.charset.html
echo "<meta charset=ISO-8859-1>";

$arr = array
( 'Hello World'
, 'Héllo World'
, 'Hello World!'

foreach ($arr as $str)
    echo PHP_EOL . $str;
    if (!preg_match("/[^a-z0-9é,\.\-\s]+/i", $str))
        echo " OKAY";
        echo " NO GOOD";
