Patch for PDO_ODBC bug causing end of string character in Unicode strings

Any queries through PDO_ODBC that return Unicode data will have an end of string character midway through the string. Wez created this patch to fix the problem but has not been able to get it into CVS because I seem to always ask him at the wrong time. Could someone take a look at this and apply the patch? I've been using a branched version with this patch for two years and would love to upgrade to the latest version. Thanks, --Travis
