   Thanks to Rick McGowan, I realized I made a mistake when adding
"(and Japanese)". I should have added '??' next to Japanese as I had some
dobuts about Japanese. Still better is I shouldn't have talked about
Japanese at all. For a moment, I forgot about the way CJK ideograms
are used and pronounced in Japanese when writting the above.

  Even for Korean(ko-KR locale), there *COULD* be a little
complexity due to that [r] cannot be placed at the beg. of word(
[n] cannot be placed at the beg. of word when followed by some vowels)
if users are not careful when converting Hangul to Hanja(a typical way
of Hanja/CJK ideogram input in Korea). For ko-KP locale, this problem
doesn't exist as they use different orthographic rules not
honoring prohibition of [r]([n]) at the beg. of word. This
complexity is by no means unique to Unicode, though.
