Korean language input

[idm0504]

Hello. I'm a Korean.
Hangul chat is not working properly.

You have to press the key twice in the chat input window.
They are entered one by one in the text box.
After that, it is repeatedly entered, but the last entered chat value does not appear. You have to press Enter or Space to see the last input.

Since Hangul has never been officially known to be a supported feature, i've swapped the bug label for the feature request one, thus, this is not a bug report, but a feature request.
