I write Hangul in IBUS in Ubuntu.
https://github.com/ibus/ibus
I can write Hangul in almost all programs such as Firefox, Chrome, Krita, GIMP and others.
But,
I can not write Hangul in this game.
I know that Korean language support is not difficult.
If this game does not support Hangul chat, I think it probably will not be long.
Also, I can not introduce games to my friends.
All I want is to write Hangul in Chat.
I do not want the game to be in Korean.
Make it possible to chat only.
I hope my wish will come true.
