Your analysis is correct.  This is a long-standing design bug in Mule,
and one of the primary applications of Han unification.  (The primary
reason is the code space limitation, of course.)

The only thing I can suggest offhand is to use M-x search-forward
rather than isearch (which is unlikely to be terribly pleased with
switching IMs on the fly, although it may work OK in GNU Emacs, pretty
unlikely in XEmacs).  Then use C-u C-\ (or C-m C-x C-\) to change to a
Chinese input method in the minibuffer.

With some work, it should be possible to create a function that reads
kanji on the fly and converts them to a character class (ie, []
regexp) that contains all Mule equivalents of the corresponding
Unicode character (ie, given a JIS character, it converts JIS ->
Unicode -> [JIS Big5? CNS? GB? KSC?] where the ? indicates that the
slot is filled only if the Unicode codepoint has an equivalent in that
character set.

It's a good idea anyway.  Give me until next week and I'll take a look
at it.  If you get something on your own, please let me know!
