I've managed to do this in one of my XeLaTeX files and now don't know how to
get the it back!

Luckily it's not important and goes back to when XeLaTeX first came out.

I did notice that there had to be a space on each side of the `=' in the
line and meant to bring that up as a possible bug. Didn't think it could
have this permanent effect on a file.

If I set the default input format to UTF-8 in TeXShop but only use the
standard ASCII set and standard LaTeX commands for accented characters as
pdflatex input will pdflatex be able to compile it; i.e., is the plain ASCII
set the same in Mac and UTF-8 encoding? What about using your French
keyboard and entering the extended set of charcters; does it need an input

Good Luck,
