What is the platform? Java? Windows CE? Something of Agilent's? It
makes a big difference. What fonts do you have?

See The Unicode Standard Version 3.0 (Addison-Wesley 2000) and CJKV
Information Processing, by Ken Lunde (O'Reilly 1999) for extensive
details. In particular, section 15.2 of the standard, Shift-JIS
Index, pp. 923-958 begins with these code points.

Neither standard has a character at that code point, but more
generally, the answer is No, there is no numeric correspondence, as
the brief quotation above shows.

No. SJIS does not have any simple ordering principle, since it
derives from encodings that have accreted blocks from several sources
over time. The order of the original CJK Unified block in Unicode is
derived from several merged radical/stroke count dictionary orders,
but other blocks will be added in future.

Hypothetically, you mean? Actually, the CJK Unified Ideographs block
starts at 4E00, and the SJIS Kanji start at 889F--with different

The Unicode web site and the CD-ROM in the standard both contain
Shift-JIS/Unicode mapping tables suitable for use in software.
