libpq + utf-8

[Лохтин Константин Сергеевич <lokhtin(at)irkutsk(dot)bnk(dot)ru>]

I met problems using libpq API with utf-8 database.
I can't figure out how to use, for example, function PQexec. This function has two parameters: PQexec(PGconn *conn, const char *command);
If the command is, for example:
  INSERT INTO mytable (column1,column2,column3) VALUES ('non-English text 1','non-English text 2','non-English text 3')
what format the string command[] should have? Should it be UTF-8, UTF-16 or ANSI(??) string?

When I use INSERT command with English data I can use ANSI string as command[] parameter and everything works fine, but when I try to INSERT, for example, Russian text into table columns, I fail using both UTF-8 and Windows1251 encoding in command[].
