Hanja to Hangul (pronunciation)

[hc27oclock]

Is it already supported in unicode? If so, we must provide in addition to this:

apply 두음법칙 to the table example: if Hanja is at the first syllable of a word, read 羅 as 나.

This phenomenon is most prominent when you sort Hanja-and-Hangul-containing lists. 羅針盤 appears after '라', not after '나' as you would expect by common sense.
