Request for help collating unicode support in DBDs

I am attempting to run through as many DBDs as possible producing a list 
of those that support Unicode, how they support it (driver flags and 
caveats etc) and any issues with it. So far I'm working my way through 
DBD::SQLite, DBD::CSV, DBD::ODBC, DBD::Oracle and DBD::Pg (because those 
are ones I have) although in truth I've not done much with Postgres as 
yet and I already have an offer from Tux/Merijn for DBD::Unify.

If you have a DBD not on my list above and know for a fact through 
experience it works (or does not work) with unicode data I'd love to 
hear from you about your experiences and if you'd also be prepared to 
run a few small scripts to your database I'd be very grateful.

Please just mail me only and I'll summarise my findings on the list later.

Thanks.

Martin
