Well, http://en.wikipedia.org/wiki/Unicode#Issues for a start :-)

Doing a bit more research it seems my statement is both dated (see for
instance http://www.personal.psu.edu/ejp10/psu/gotunicode/japanese.html)
and quite inaccurate (according to
http://www.unicode.org/versions/Unicode5.0.0/ch12.pdf, the semantic
component is only one of three primary attributes used when deciding to
unify a character - tables 12-5 and 12-6 I found particularly helpful on
this front).  It was largely hearsay I must confess.

Anyway, this is a bit off-topic, and

avoids the issue entirely.
