Обсуждение: Support unicode in libpq

Hello:

I would like to know how libpq library support with the unicode query? As I
find that it accepts char string only e.g. PGresult *PQexec(PGconn *conn,
const char *query)

How can I handle if the query contain the unicode which is of wchar type?

From my experience with psycopg (the python binding)
you get always 8-bit chars. They are encoded depending
on your actual client encoding:

select pg_client_encoding();

I decide on that encoding wether its unicode or not
and if its unicode decode it from utf-8 to unicode.
I think the same could be done in your case.
