6.10.3 Non-multilingual Issues
Non-multilingual partitions can only work when the system codepage on Windows is matched to the default job CCSID of the logged in user on IBM i. For example Japanese Windows codepage 932 with Japanese IBM i CCSID 5035 will work but English Windows codepage 1252 with Japanese IBM i CCSID 5035 will not work.
The reason for this is there is no override field X60CHR to specify the codepage/CCSID to use so LANSA can only use the current or system codepage/CCSID.
