Can't find character, but can replace it?

Can't find character, but can replace it?

[djc]

On switching to GNU Emacs 23.1.1 (i386-mingw-nt5.0.2195) from 22.3,
suddenly emacs can't find the character \0363 (decimal 243), small o
with acute accent -- neither with "search-forward" in elisp code, nor
with "search-forward" bound to a key.  (Or perhaps others, but this is
what I happened to notice.)

But replace-string can find and replace it.

What am I missing here?

i cant reproduce this. e.g.

what ó thewhatóthe

interactive search finds it.

It is absolutely reproducible on my system.

Maybe you have too much? (In your init file.) How does it work when  
you launch GNU Emacs with -Q or with -q?

That's it: with -q the problem doesn't appear.  So thanks for the
help: it's very useful to have someone look over my shoulder and
remind me of the obvious.

Now to debug my init file!

The problem was in one of my customization entries:

    '(enable-multibyte-characters nil)

When I disabled that, emacs once again behaved as I expected.

The other behavior is confusing.  Worth a bug report?

By commenting or removing this line you did not disable anything but  
*enable* GNU Emacs to work correctly, use UTF-8 (with usually more  
than one byte for one character).

To yourself? Read the documentation and understand that you are using  
a multi-byte/Unicode application. Unibyte can easily be accomplished  
by using an environment variable like LC_CTYPE with a value that  
corresponds to some 7- or 8-bit encoding.
