%D The conversions comes down to (for the sake fo speed the
%D implementation combines steps):
%D
%D \startitemize
%D \item we expand the \UTF\ sequences into \type {\unicodechar}'s
%D \item spaces become character 255's (so that they are not
%D gobbled in argument fetching
%D \item normal \ASCII\ chars are unchanged
%D \item \par's and alike are converted to \type {\unicodechar}'s
%D \stopitemize
%D
%D This happens by expansion; next we convert the resulting
%D sequence by interpreting the stream.
