% Computer Modern Roman upper case with dotted diacriticals for Turkish etc.
% These letters were originally coded by D. E. Knuth in November, 1979,
% inspired by the Monotype faces used in {\sl The Art of Computer Programming}.

% Sans serif designs by Richard Southall were added in April, 1982.
% The programs were revised for the new \MF\ conventions in 1985.

% Dotted diacriticals added by P. A. MacKay, January, 1987.

% Upper case letters with accents above are all given the height
% value |body_height|, with the result that the accents kern up
% into the white space or leading from the previous line.  It is
% the responsibility of the formatter to set TeX's baselineskip
% so that there is adequate room for such accents.  The cup on
% upper case G is probably the most extreme case in serifed roman
% or italic fonts; the hat on O is the most extreme in sans-serif
% fonts

% Character codes \000 through \012 are generated.
