Hello.
Some Minecraft Version ago
(I think the Version before the Horse Update)
I realized that the German Umlaute ä , ö and ü
don't work anymore in the chat .
This is a problem in Multiplayer , Singelplayer , Command Blocks and Anvil .
There also is a bigger problem . The ~ Sign doesn't works .

Thank you for reading . I hope this will be fixed when I download the next snapshot
Keep on doing your awesome work .
