My personal preference would be to disallow single jamo
(or maybe even all jamo; they are not needed unless you
want domain names for single jamos, or if you want domain
names with historic hangul, both of which doesn't make
much sense for me).

How is anybody going to decide which characters in which local
charsets are 'special'? I haven't read KSC5601, but I'm assuming
it doesn't mark characters as 'special' or 'normal'.
