You don't. Those are not valid characters for use in domain names currently.

You can't register with these characters on all domain-names, such as .com if Im not mistaken. You might want to look into .nu-names which I think allows those characters. It is really not that recommended though.

Read http://en.wikipedia.org/wiki/Internationalized%5Fdomain%5Fname. First of all, many characters are not permitted in IDNS. Secondly, the recent announcement is that registration will open for a limited set of IDNS names in a few months, not now.

Check out Iwantmyname. It's possible for .WS and .LA as far as I know.
