I personally would be satisfied for the runtime logic to just raise an LE error condition and dump for any sort of conversion-stopping error. So long as normal “character not defined in the requested EBCDIC CCSID so make it SUB in the output” issues are just done without asking, I am perfectly willing to scan the result for SUB characters myself and use application-dependent error logic to handle or ignore the result as needed.
