What may be on-topic for the ietf-languages list is to remind people
that there is *no* way to do *automatic* transliteration to ASCII in
most cases.

Proven&#xE7;al => Provencal is an easy case, but there is no general
rule to do such a conversion from Unicode to ASCII. (And specially no
standard rule, for instance, there is no standard way to transliterate
Arabic characters to Latin characters: english-speaking people write
"Iraq", french-speaking write "Irak" and so on.)
