Another possibility would be to update the fonts-android-udeb package to ship DroidSansFallback.ttf instead of DroidSansFallbackFull.ttf, which seems to do the job for Korean. But I don't really want to risk triggering regressions for other languages, so adding a fonts-nanum-udeb package would seem like my preferred path right now. Nevertheless, having checked the file size now, that means adding a 4.2 MB file, which doesn't seem too good either. :( Comments/suggestions most welcome… KiBi.
