I never put them in C code, but I do often have some in text and LaTeX
files: the French typography rules uses more spaces than the english
ones, in places where one shouldn't break lines (before :, !, ? and
inside « French quotes »). Real typographers would distinguish short
non-breaking spaces and normal ones, but I usually don't ;-).
My editor shows them as a space underlined in slight color. One can
reproduce this in a terminal with things like
echo -e '\033[3;4m ' # no color
or
echo -e '\033[1;4m\033[1;31m ' # red underline space
That's lighter than full red background, hence acceptable as a warning
that people who purposely use   can ignore.

A common typo for French people is to type
foo | bar
^
since the | needs Alt-gr on azerty keyboard, and Alt-gr + Space gives a
. Particularly painfull to diagnose since the shell answers e.g.
zsh: command not found: bar
{ and } also requires Alt-gr, so I can imagine someone typing
if (foo) {
^
by mistake.

I often see them too, I guess the mailer does this to prevent other
(broken) mailers from rewrapping, but I don't like it either.
