%
% Oct. 2012: More robust macros by \long, \noexpand, \badutfinput (P.O.)
%
% This macro sets all others UTF-8 codes (not declared formerly or
% later) as "unknown" by encTeX primitives. You need the version
% Feb. 2003 of encTeX or later.
%
% You can re-define the \warntwobytes and \warnthreebytes macros
% if you need it. The default value of these macros is that
% the black box is typeset and warning is printed by \message
% and the unknown code is printed without any change to \write files.
