@Kumasasa There is no problem on translation.
If that message appears or I copy & paste '쉴'(U+C274) into chatbox, Minecraft shows me the letter '숼'(U+C23C).
That translation is perfect.
But, in Minecraft 1.6.4, it shows me wrong letter.
@Kumasasa It's not translation request. This is Error report.
And, I already checked translation project at Crowdin.
But why that /seed command is still displayed as /시드 in Minecraft 1.7.2 release?
