Full unification here would have the disadvantage that CJK Greek/Cyrillic
characters are traditionally displayed as double-width, whereas ISO
8859/ISO 10646 Greek & Cyrillic characters are traditionally displayed
single-width. Some CJK users might be quite happy about a lack of
unification here to preserve the display width of these characters. Same
for the block graphics characters, which xterm with ISO10646 fonts
displays single-width whereas kterm with JIS/etc. fonts displays in

But surely all the European encodings such as ISO 8859, KOI, etc. should
be urgently unified with Unicode. The relevant standards have already been
(re)written to represent these encodings just as single-byte encodings of
ISO 10646 subsets.
