Hi all!
Recently I tried to use the new 7.02.0001 Win32 ODBC driver in the new
(beta) Unicode mode in conjunction with MS Access 2000 and a "UNICODE"
encoded database stored in a PostgreSQL 7.2.1 database running on a
Linux system.
I noticed that when the "LF<->CRLF Conversion" option is *enabled* in
the driver's settings dialog, only a CRLF->LF conversion (while writing
to the database) is performed, but no LF->CRLF conversion (while reading
from the database)!
I thought that this might be a bug, and thus downloaded a local copy of
the ODBC driver sources from CVS. I searched a bit and AFAICT found the
reason for the ill behavior, so I made a patch.
Julian.
