This may be getting somewhat OT, but it should be noted that the
above recommendation for Old Hangul is in conflict with NFC. From
http://std.dkuug.dk/jtc1/sc2/wg2/docs/n3422.pdf:

2) A Wanseong syllable block cannot be recomposed with Johab Hangul letter(s) to represent
another Hangul syllable block.
- an example. ?? (U+AC00 U+11EB, incorrect) ? (U+1101 U+1161 U+11EB, correct)

NFC would result in U+AC00 U+11EB, not U+1101 U+1161 U+11EB.
