Characters from other language in Summoner Name?

I want to know why can't we use characters from other languages in our summoner name. I do understand that not everyone might understand it's meaning if we use characters from, for exemple, Korean, but I personally think that other don't really need to understand, since we have random names anyways. Also, IGNs identifie us; thus if we are limited to roman characters, we are denied of our full right of expression and identity. Just like a real person's name, it's not because we are in NA that we need to have a English name.

I know there are technical issues involved, like characters not displaying or are displayed as boxes; and there are bad word filter problems. But I truly believe that by allowing us to use special characters, players can come up with creative name, create a more dynamic community, and most importantly more fun.

I believe (I hope) that technical barriers related to locale and fonts are easier to overcome than game breaking bugs, server issues, and what not. I do hope that Riot consider this.

If nothing will works for the current state of the client, I propose that we get 2 parts in our summoner name: the first part will be unique for each summoner (like a tag or prefix) and the second is our nickname, which allows the use of special characters. People won't have problems identifying other players, and it lets us be more creative with our summoner.

Sorry for bad English.
