On the new client, you can't set your custom status message in Korean/similar languages.

I am a Korean speaker, and I have discovered after trying to set my status message in Korean, that the client recognizes it as "mature language." On the old client, it wasn't a problem to put enter your status in foreign languages, which is why this upsets me. This is a very small change that doesn't impact the game whatsoever, so hopefully a Rioter will see this and result in a fix. :)
