+% Feb. 6. 2003 Petr Olsak
+%
+% 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.
