Then tell them to use JIS X 0221 instead of Unicode! Since it is a
Japanese National Standard they'll be pacified into using it, even
though it is nothing more than the Japanese translation of ISO/IEC
This is becoming a bit of an urban legend: while it is true that
during the initial Han unification period for Unicode 1.0 there was
pushback from the Japanese who thought that characters were being left
out. This issue is one of glyph variants between Japanese kanji,
Simplified and Traditional Chinese hanzi, and Korean hanja: the same
character can take different forms in each of these locales.
Remember that one of the criterion for the Unified ideographs was that
mapping between legacy encodings and Unicode can be accomplished. If a
character can be found in an existing national standard (in the case
of Japan), then chances are that code point is found in the Unicode

But most, if not all, of the commonly used characters *are* available
in Unicode 3.0. It is rare, especially for Japanese, to find words
that cannot be encoded in Unicode.

Extension A is part of Unicode 3.0 and will be in the BMP when ISO/IEC
10646.2000 is released.

Especially true when dealing with the Hong Kong Supplementary
Character Set (HKSCS). However, the HKSAR provides mapping tables for
between Big Five and HKSCS and ISO/IEC 10646.1993 and .2000 (two 10646
tables are required since some of the code points in the HKSCS are
included in IEB-A --- the rest should appear in IEB-B). The problem is
when you want to transcode between Chinese encodings: you cannot go
from HKSCS to GB2312 or GBK --- the mappings simply do not exist.
