If the ActionScript language spec says the characters are allowed, then
metaas should really be supporting them :)

It might be quite simple to add support, depending on the part of the
grammar needing modification.  One thing though; at least in the email
as I saw it at this end, some of the characters didn't look like those
that I understand appear in normal French usage.  (my understanding *is*
poor, however :)  For instance the small-letter-a-with-underscore
character, described in my character-map utility as "Feminine ordinal
indicator - Spanish" -- is this also appearing at your end?  Was this a
character in your code somewhere, or is there a problem with the handling
of encodings too?

If you would let me know where in the source code you are using
non-ascii characters (e.g. in string literals, in variable names, ..?)
I'll look at adding support in that area first.
