There are 2 problems with multiable encoding methods 1. Display S360+ has special hardware support for converting binary / decimal to/from display EBCDIC. Any other encoding for display is roll your own. 2. Compares of hetrogenious data is not supported by hardware "0" ebcdic does not equal "0" ascii S360 has always had an instruction to facilitate conversion from one encoding method to another. The instruction is called TRANSLATE. Translate however requires a code table which is 256 bytes long. The value of BYTE x is used as an index to the table which has the translated value for X at that location. The problems are a. it is a user provided table b only supports single byte characters.
Unicode services is ment to provided some standardization of this via software. It should be noted that the conversion is complicated by hardware as the encoding required by software (so compares work) may be different than those required by I/O devices such as ASCII terminials.
