No, sorry, they are not. See

  CHARSET
           BASESET  "ISO Registration Number 177//CHARSET

The line "128     32      UNUSED" excludes them, or doesn't it?

Actually, these code positions are valid (though rather useless)
in XML, but they are invalid in HTML. So I'm not sure what the
result is for XHTML.
