failure of the \= regexp in buffers with non-ASCII text

This is driving me nuts. The regexp \= (match empty string at point)

Thank you for the report and the recipe!
I can replicate the case with your example of M-C-s \ = in the mail
presentation buffer, and with M-: (re-search-forward "\\="), but it
works fine with M-: (looking-at "\\=") RET.
For now, is there any chance you can work around with `looking-at'?
I've added some tests for this locally (need to test the tests :-),
but when I tried to get at it in the debugger, for some reason
(optimization, I bet) I've been unable to hit the problem code with a
breakpoint. The function is several thousand lines long, so just
stepping isn't going to be much fun.... It may take a bit to get this
fixed.
