It was in an earlier message in this thread. It was also in several previous
educational exchanges we have had on this topic on news groups :-). Look on
Symbol Font Substitution (Macintosh)
The Macintosh character set includes a number of math,
Greek,and Pi characters that are not contained in most
fonts. ATM software and PostScript printer drivers
routinely re-encode text fonts (those marked for
re-encoding) to "borrow" those characters from the
Symbol font. If some of those characters are included in
the font, the user will see, instead, the characters
substituted from the Symbol font. No such substitution
occurs with ATM or printer drivers for Windows.
% notequal, lessequal, greaterequal, approxequal, partialdiff, integral
% summation, product, pi, infinity, Delta, Omega, radical, lozenge, apple
The folllowing `math' glyphs, on the other hand, now do exist in most text
% degree, plusminus, mu, logicalnot, divide, fraction
Typical Type 1 text fonts contain (21) other glyphs not accessible on the Mac:
% Lslash, lslash, Scaron, scaron, Yacute, yacute, Zcaron, zcaron,
% Eth, eth, Thorn, thorn, brokenbar, minus, multiply
% onequarter, onehalf, threequarters, onesuperior, twosuperior, threesuperior
In addition, Mac TrueType fonts now contain another 11 glyphs:
% Scedilla, scedilla, Gbreve, gbreve, Cacute, cacute, Ccaron, ccaron,
% Idotaccent, franc, dmacron.
% This is where it stops since the Mac cmap is limited to addressing the first
% 256 glyf in a TrueType fonts.
