Korean encoding problem

I have bug reports regarding encoding. It has been a while since I found out about this issue. The encoding is okay but quite often the encoding is not working and it is showing weird word instead. It is showing in random places at random time for random character.

Any solutions? I hope that you guys can reply me asap thanks!!

Hey @hj.lee.

It would be nice to see minimal reproduction code, so we can see the issue.
