The upgrade to Zend Server for IBM i version 8.5 or higher includes an upgrade to the ibm_db2 version 1.9.7.  This version changes the default settings for a couple of the ibm_db2 configuration directives.  One of these settings, ibm_db2.i5_override_ccsid, prevents the automatic correction of certain CCSID characters.  This can improve performance, but in some cases can cause international characters to be rendered incorrectly.  Messages indicating "can't convert from 1208 to 65535" may be seen.
