But this approach will require changes in packages/odbc/src/odbcsql.inc 
like, does not ?:
-    pointer(SQLGetData) := 
GetProcedureAddress(ODBCLibraryHandle,'SQLGetData');
+    pointer(SQLGetData) := 
GetProcedureAddress(ODBCLibraryHandle,'SQLGetDataW');
And I do not know how it affect compatibility for example in UNIX or if 
all ODBC drivers support this functionality.

But also in this case we will get UTF-16 widestrings (in Windows) not 
UTF-8, does not ?
