IPS 4 Profile URL - lack of unicode characters

[AL|EN]

Hi,

Again, I want to point that there are no Unicode characters in IPS 4 Profile URL.

IPB 4: http://community.invisionpower.com/profile/537304-alen/

vB 5: http://www.vbulletin.com/forum/member/468680-al|en

I don't like this filtering as it may lead to confusion between "AL|EN" and "Alen"
