OK, I was envisioning something like that:
http://search.cpan.org/~sburke/Text-Unidecode-0.04/lib/Text/Unidecode.pm
but now that I think of it, I can always just write a plperlu function
that uses that module. The only inconvenience is having to have plperlu
in the db, but I can live with that.
Postgres extensibility rocks and I rest my case.
