% Most of  these  glyphs  were  designed  by  Silvio  Levy;  CB modified and
% "corrected" most of them in order to be valid for all family, series, and
% shapes; he added also the per mill and the euro signs, plus two invisible
% characters. For the CB romanstyle Greek alphabet he modified the open and
% closed quotes so as to look like the "English" raised quotes; may be this
% is a little detail that breaks up with Greek typesetting tradition, but
% this is what appears with no doubts from the printed pages of the magazine
% Nemecis, where CB got the idea of the CB romanstyle Greek fonts.
