% A tab (^^I) prints as lowercase gamma.
% Character ^^M could be made visible, with a bit of work;
% at present, it's indistinguishable from newline (^^J).
% You can get up to 103 characters on a line without an overfull box.
% 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
