And what does ISO say about the character set?

I don't have the ISO standard, but I've seen various documents that
seem to be carefully worded so as to allow EBCDIC, e.g.
http://www.opennc.org/onlinepubs/7908799/xbd/charset.html

But clearly you have to use US-ASCII in network protocols, so it can't
be much fun getting most programs to work on an EBCDIC system ...

The usual advice is to use the wchar_t API, let the system libraries
handle it and avoid putting anything UTF-8-specific into the
application.
