The ODBC extension did not support WVARCHAR. WVARCHAR ends up being handled by the default handler where vallen is set by the driver to the actual bytes needed for the field. If it is larger than default-lrl then the output is corrupted (reading past the buffer) because the return functions don't expect that to happen. The patch add support to handle WVARCHAR just like a regular VARCHAR.
