I have a text file that was mangled at some point - the accented
characters have the wrong byte value (e.g. � is \201). Emacs also
does not recognize this as any particular encoding, so it uses the
\201 notation for the 'bad' characters.
When a replace-string is started, entering \201 (copy-yanked from the
buffer) aborts emacs.
gdb results:
