[idn] time to consider average han/hangul domains

["Soobok Lee" <lsb@postel.co.kr>]

Now that we have many useful ACE alternatives to overcome
"15 han letters barrier",
it is time for us to consider the reducing length of ACE labels for
AVERAGE han/hangul domains.

As the next example shows,
LDUDE produces 15 chars ace labels for a 9-letter hangul domain.

9 letters Han/Hangeul domains are very common.
