I think you could be using PQexecParams() and passing your wide-char strings as binary parameters somehow. I don't really know if this will work or not, but it may give you an idea. But note below: > Even if somehow if I convert wchar_t * to char * and provide it to > Postgres, how will it differentiate between chinese characters and normal > characters ?? Please note that any string you pass from the client will be interpreted using the client_encoding setting. So maybe what you have to do is just set client_encoding to the encoding that the strings are encoded in. If you choose the wrong client_encoding, the server may recode the characters inappropiately, or not at all, and thus insert wrong data.
