PCRE - National characters

Hi :)

Now have i tried to solve my reg exp problem - but nothing seems to work.

I want to find all non-letter chacters of a word - and replace it with
nothing. It seems to work - but when I begin to add national characters
to the strings - it doesnt work...

A simple part of it could like like this

<?php
$foo = "æble";
$bar = "Ja?";
echo preg_replace('/\W*/', '\1', $foo); //returns ble - hould return æble
echo preg_replace('/\W*/', '\1', $bar); //returns Ja
?>

Isnt there a way to solve this problem? Or is \w limited to a-z?

:)

Regards,
Johan

Funny, never realized that national characters were a part of the word
characters lot. You might want to try:

<?php
$foo = "æble";
$bar = "Ja?";
echo preg_replace('/[^a-zA-Z]*/', '\1', $foo)."\n"; //returns ble
echo preg_replace('/[^a-zA-Z]*/', '\1', $bar)."\n"; //returns Ja
?>
