How to write non-English letters in my name

Well .. apparently there are many ways. My name is written like this 

Matjaž Kljun

But when the keyboard lacks special letters you can always compensate with other non English letters like my colleagues do

Mątjăz Kljún

Or like this

Mätjåz Kljũn

I suppose both are still better than Nat Jazz 🙂
