Does that help ?
I'm not sure how your question relates to UNICODE. If the data on the PC (Windows, I assume) is in some encoding of UNICODE, then code pages don't really come into play. Any version of Windows can (in theory) use any UNICODE character, regardless of the country or language of installation. So there will be no difference between the way a US English Windows box encodes, say the dollar sign character and the way a French French one does. The UNICODE code point for dollar sign is U+0024, and that's that. But you also mention ASCII, which (loosely) is an 8-bit encoding. (Usually ASCII these days really means some single-byte code page such as ISO 8859-n or one of the Windows ones such as 1242.) There is no general way to convert UNICODE into EBCDIC, because no IBM EBCDIC code pages encodes all UNICODE characters. And if you are talking about single byte EBCDIC code pages such as 037 or 1047, IBM's generally encode 192 characters, vs tens of thousands in UNICODE. If your PC data is in "ASCII", i.e. single byte encoding, then you have to both determine the code page in use on the PC, and the one in use on your z/OS, and then use the appropriate mapping. Such a mapping may not exist. For example, if your PC is using a Polish code page, and your z/OS a Western European one such as 1047, there are characters in each that just aren't in the other. Something will break - generally someone's name will be misspelled, or worse. Maybe you can give a short example of what data you have at each end, and what you want to happen to it.
