print charblock (0x30a0);
Great.
But that is not good enough for cases below because...
(Hiragana | Katakana | Han) => 'jisx0208.1990-0'
This is very wrong because jisx0208.1990-0 only contains \p{Han} that
appears in Japanese (JIS X 0208, to be exact). On the other hand,
jisx0208.1990-0 does contain greek and cyrillic alphabets.
One of so many reasons why Han Unification was a bad idea. When it
comes to Han Ideographs, Unicode's sense of charscript is almost
useless.
