Another wrinkle to this is the fact that identifiers in the database, such as column names and such, are also character data, and have an encoding. So for any DBMSs that support Unicode identifiers (as I believe a complete one should, even if they have to be quoted in SQL) or identifiers with trans-ASCII characters, we have to account for those too, making sure that the various Perl-side code correctly matches or doesn't match those identifiers, and so on. -- Darren Duncan
