An essential reference for everyone interested in the subject:
The ISO 10646-1:2000 standard prints the entire CJK collection in 5
different ideographic fonts and comes with an appendix that documents
the principle and rational behind the CJK unification in detail.
Available from
http://www.iso.ch/cate/d29819.html
in PDF on CD-ROM for just 80 CHF (~45 USD).
In my opinion, the CJK unification is something that should already have
been done much earlier in the 1970s when the first ideographic character
sets were standardized. Unfortunately, these projects were initiated
only at a national level and the authors of the standards didn't talk to
each other even though they worked on a highly overlapping character
repertoire. Only in the late 1980s, the Chinese standards body started
to work on CJK unification, which led in the end to the GB 13000 draft,
which again was later incorporated into Unicode and ISO 10646. (see also
Unicode 3.0, Appendix A)
