I've been waiting for a go-ahead from folks who would use it. imho the
way to do it is to use Postgres' type system to implement it, rather
than, for example, encoding "type" information into each string. We
can also define a "default encoding" for each database as a new column
in pg_database...

Red Hat built their RPMs with locale enabled, and there is a
significant performance hit. Implementing NCHAR would be a better
solution, since the user can choose whether to use SQL_TEXT or the
locale-specific character set at run time...
