Linus Torvalds f313bcf64a Add support for a "utf-8" mode
NOTE! MicroEmacs is very much a byte-based editor, and the new utf-8
support is purely an issue of terminal input and output.  The file
contents themselves are in the 8-bit space.  In that space, Unicode is
the same as Latin1.

The new mode is called "utf-8", and is enabled automatically by the
new emacs.rc when $LANG contains the substring "UTF-8".

I'm sure people would like to some day also edit real UTF-8 contents,
rather than just edit old 8-bit Latin1 contents in a UTF-8 terminal.
However, that's an independent (and much bigger and thornier) issue.
