I read SUS v3 and there is no hint on multi-wchar anything, so for unix systems you are right, wint_t == wchar_t. Seems stories how Windows and Java operate have affected me too much. Then I browsed MSDN: http://msdn.microsoft.com/en-us/library/dtxesf6k.aspx and they seem to strongly hint that wchar_t == 16 bits and UTF-16 is used internally. Probably some Windows developer should look into it and decide if there is a #ifdef WIN32 branch needed. -- marko -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
