% NOTE: This particular file has been customized for TeX n ANSI encoding
% NOTE: If your text fonts use TeX 'n ANSI, then \input texnansi.tex as well.
%
% This is `encode.tex', were you customize `mtmacs.tex' to the character
% encoding used by your DVI driver for the Times text fonts when used in math.
%
% NOTE: this ONLY changes the behavior of text fonts when called for in MATH.
% It does not deal with the character encoding of text fonts used outside math.
%
% Uncomment the lines that apply to the character encoding you use, or
% add new lines if the encoding you use is not one of the examples given.
% Character codes may be given in decimal, or hex using ", or octal using '
%
% You will typically also need to do something about encoding of text fonts,
% since plain TeX and LaTeX have the CM `TeX text' encoding hard-wired in.
%
% Examples are given at the end of different encodings (mostly commented out)
