Conversion from an Alphanumeric CCSID to a Graphic CCSID might not convert all characters successfully.
0
Cause . . . . . : When Alphanumeric data is converted to Graphic data, the data between the shift characters is assumed to be in the double-byte CCSID related to the Alphanumeric CCSID. If the double-byte CCSID related to the Alphanumeric CCSID is different from the target CCSID, double-byte characters in the source data that are not in the result character set cannot be converted successfully. The conversion will result in a substitution character being placed in the result data.
