More and more people are adding obscure letters to their name with tildes and accents over particular characters. Unfortunately, most of us live in countries that don't mass produce such characters on their keyboard. Rather than having to research their guild to find them, or research the ALT+ char key combination (or even find a place to copy and paste it from), I think it would be awesome if a small character map dropdown box was added. Simply something next to the search field with the most commonly used or even all of the possibilities for the more unique characters allowed in WoW.
This would alleviate a lot of time trying to look up people, specially with my original friends who cannot create a unique name ;p
