% Further notes from Don, January 2017:
|
|
%
|
|
% Maybe I'm the only person left who still uses plain TeX in a UTF-8 world.
|
|
%
|
|
% But for what it's worth, I'm appending a little file that I prepared today,
|
|
% since it turned out to be useful in a project of interest to me.
|
|
%
|
|
% Namely, I've got a program that takes an XML encoding of organ-pipe
|
|
% settings, used by performers when they change the stops during a
|
|
% performance, and translates it into a human-readable form.
|
|
% I mean, the output says "when you reach combination nunber 0013,
|
|
% the following ranks of pipes are set to play".
|
|
%
|
|
% The names of those ranks of pipes often contain accented characters,
|
|
% as well as things like the German \ss. In order to use such texts on the Web,
|
|
% I have them in UTF-8 code. But to make a verbatim hardcopy listing using
|
|
% nice typewriter-style fonts, I wanted a program like "list.tex", which
|
|
% I've been using to print text files for more than 25 years.
|
|
%
|
|
% Fortunately, the accented characters all turn out to be two-character
|
|
% sequences in UTF-8, where the first character is always '303. So I
|
|
% can simply make that character active, and it can then change the
|
|
% following character appropriately.
|
|
%
|
|
% Therefore I added a few lines to "list.tex", resulting in "list-latin.tex".
|
|
% And it works! Hence it might be a useful addition to the CTAN archives.
|
|
%
|
|
% Yours truly, Don
