Some change after 2008-05-29 has resulted in strange behavior of
non-ascii characters in string in Emacs Lisp mode.  I have an elisp file
that contains the string "§" (that's the section charater, unicode
U+00A7).  When I visit that file in my Emacs builds from yesterday or
today, that character appears as "§" (backslash 247).  C-u C-x = says
this:

        character: § (4194215, #o17777647, #x3fffa7)
preferred charset: eight-bit (Raw bytes 0-255)
       code point: 0xA7
           syntax: w 	which means: word
      buffer code: #xA7
        file code: not encodable by coding system utf-8-unix
          display: no font available

Yet I can type "§" (the section character) in Emacs Lisp mode in these
builds and it appears as it should and describe-character recognizes it.

Then, in my build from 2008-05-29, which does not have the above
problem, I wrote an elisp file containing the following string:

"§ßäöüµ" 
(in words: section German-eszet a-umlaut o-umlaut u-umlaut mu)

When I visit that file in my builds from yesterday or todo I see this:

"§ßäöüµ"
(in words: A-with-circumflex section A-with-tilde \237 A-with-tilde
currency-character A-with-tilde pilcrow A-with-tilde one-over-four
A-with-circumflex mu)

When I change this file (but not the string) and resave it in my
2008-05-29 build, and then in the newer builds invoke revert-buffer on
that already visited file, the string changes to the same as in the
earlier build, i.e., the characters now look like they should.  If, in
these newer builds, I now kill the buffer and then revisit the file, the
string no longer looks strange, but the same as in the earlier build.

I am using the Xft font backend and start Emacs with -fn "Dejavu Sans
Mono-10".

Sorry, I embugged yesterday.  I've just fixed it.
