Update: Korean chat is no longer cut off

The launcher downloads this update the next time you start the game. If the game is open, close it and start it again.

Korean chat: since the client moved to Unicode, a Korean letter takes three bytes where it used to take two, and the game kept counting the old way. A long Korean line overflowed the chat box, and the speech bubble over your head showed only six letters per line and wrote the end of the sentence over its beginning.
The chat box now stops at 100 English letters or 33 Korean letters, which is as much as one chat message can carry, and the speech bubble shows 10 Korean letters per line, as the original game did.

Thanks to King for the report.
