% Warnings for all undeclared UTF-8 codes
% =======================================
% Petr+Mirek Olsak Sep. 2009
% Note: this file is an old version of utf8unkn.tex which is currently
% used by csplain by default (since Dec. 2012). If you are using
% csplain then you need not this file (utf8unkn.tex is preloaded already).
% This file is saved in enctex package only for archive purposes.
% Petr Olsak, May 2014
% Suppose, you are using encTeX for reading UTF-8 codes in input.
% Possibly, not all UTF-8 codes are declared by \mubyte..\endmubyte
% in your macros. You can do
%
% \input utf8warn
%
% in order to print warning messages for all undeclared UTF-8 codes
% scanned in input. The \mubytein have to be positive, of course.
%
% If undeclared UTF-8 code occures in input, the message
%
% WARNING: UTF-8 code <native-code> (^^hexa-code) is undeclared.
%
% will be printed on terminal and into log file. The \failedchar
% (implicitly defined as black box) will be printed into document.
%
% Example: WARNING: UTF-8 code “ (^^e2^^80^^9c) is undeclared
% means that double quote is not declared in your \mubyte table.
% You can correct it by adding (for example):
%
% \mubyte \leftqquote ^^e2^^80^^9c\endmubyte
% \def\leftqquote{``}
\ifx\mubyte\undefined
\message{SORRY: the encTeX have to be active to use this macro}
\endinput\fi
% \warntwobytes, \warnthreebytes etc. will be inserted by encTeX before
% all undeclared UTF-8 codes:
