So is this a Bug 13829 dupe?
Going by what that part of winetricks does, as long as you did have a Korean font already installed before (I don't really see providing a specific font should be wine's job), I'd say it's more along the lines of what I've wrote in bug 52697 - font substitution in wine just isn't sufficiently complete.
Maintaining a hardcoded list of standard Windows fonts that potentially need substitution should fine, as long as you don't hardcode what it should be substituted to. Though my feelings are that wine would have to end with something similar to pango and that's beyond tricky - even now pango doesn't do certain things properly (for example maintain monospace across lines).
