Most Emacs source files are encoded in UTF-8 (or in ASCII, which is a
subset), but there are a few exceptions, listed below. Perhaps
someday these files will be converted to UTF-8, for convenience when
using tools like 'grep -r', but this might need nontrivial changes to
the build process.

* cp850
This file contains non-ASCII characters in unibyte strings. When
editing a keyboard layout it's more convenient to see 'é' than
'\202', and the MS-DOS compiler requires the single byte if a
backslash escape is not being used.

recommending UTF-8, but these files haven't been converted yet.
