When the UTF support is not used, the hexadecimal value generated by the compiler for the character \n and used by the run time has two different values. The hexadecimal value 0x15 is used if SYSIFCOPT(*NOIFSIO) is specified on the compilation command. The hexadecimal value 0x25 is used if SYSIFCOPT(*IFSIO) or SYSIFCOPT(*IFS64IO) is specified on the compilation command. When the UTF support is used, the newline character in UTF-8 will be hexadecimal 0x0a regardless of what SYSIFCOPT value is used.
