I'm trying to write something with some Chinese, Japanese, and Korean in it. As you may know, among the three, Korean is the one that requires spacing between the words, but not the other two. I have the code written as above, and for Chinese and Japanese, the result is as expected, with spaces, but for Korean, the spaces in the last line are ignored.
I've read the other post about putting spaces between Korean words, but it doesn't seem to work for me. So I have no idea what I'm doing wrong.
