Se my response to Chris Wendt's mail.
By true subset I mean that both characters and code values must match.
Then only ascii and iso 8859-1 (and Unicode) are true subsets of UCS.

I am doing that, but often it results in the program able to read/write
ascii, UTF-8, UCS-2 or UCS-4 and not iso 8859-1 which is, like ascii, UCS-2
and UCS-4 a directely coded subset of UCS.

As long as we cannot get programmers to understand that their new
programs must still be able to read and write the text currently in use,
it will be very difficult to use the programs.
