Answer 1

I think there is no way to achieve that as URL notation does not allow special chars.

Would it be a solution for you to remove accentuated characters ?

Answer 2

Trust me, these URL are really help you in SEO, especially in Vietnam. It's look very long and hard to remember, but you can use like http://gmpvietnam.com/12/ instead of http://gmpvietnam.com/12/blablatext

A site with Vietnamese and it did very well.
