Regex æøå email validation?

[Søren Neigaard <soeren@xxxxxxxxxxxx>]

Hi guys

Im helping a friend with hes internet site, and I have found this  
regex email validation regex on the internet:

var filter=/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a- 
z]{2,6}(?:\.[a-z]{2})?)$/i;
if(!filter.test(email)) {
	return false;
}

It works fine, but my friend strangely enough has users with special  
danish letters (æøåÆØÅ) in their email address, and that it does not  
accept. Regex is black magic to me, I have tried to modify it in  
different ways, but with no luck.

I know its not PHP specific (its JavaScript), but maybe one of you  
can help me anyways?

Best regards
Søren
