Subject: 23.0.60; Unicode search bug
Date: Sun, 06 Jul 2008 21:43:23 +0300

There is a weird bug in searching Unicode text.  The search function
fails on Cyrillic letters between codepoints #x0400 and #x041f, but
successfully finds a Cyrillic letter between #x0420 and #x042f.

I tried to debug this and see that in case of failure
it calls `boyer_moore', and in case of successful search
it calls `simple_search'.  I checked the Unicode properties,
but everything seems correct.

This bug didn't exist before the Unicode merge.

The easiest way to reproduce it: run `emacs -Q',
put in the *scratch* buffer the following 4 lines
(note the leading space):

(search-forward " П" nil t)
(search-forward " Р" nil t)
 П
 Р

and type `C-x C-e' after each of first two lines.
