Apple Macintosh Korean Language Kit - Manual (Page 20)

If you have selected a Korean font for file and folder names, you can also
change keyboard layouts while working on the desktop. For instance, if you
want to edit a Korean file or folder name (and you have set your system
font to Soeul), you need to select a Korean input method before inputting
Korean text.
