I know you got around your problem, but...

See the Info Node: `Mathematical Text' for allowed stuff.
Unfortunately, accented characters are not included.

However, If it be be done in PostScript, it can be done in Gri.
I looked into the iso-latin font encoding in Postscript and
figured out out to make PostScript display their characters
correctly.  I have sent the PostScript snippets to Dan Kelley,
the author of Gri, and he says he'll include this in a new
version shortly.  We might have to do something like:

 set font "helvetica-isolatin"
 draw label "bonne journée" at \
   ..xmargin.. {rpn ..ymargin.. ..ysize.. + .5 +}  3 cm

to get it to work, but it will work shortly.
