-% Idea is to have all the characters normally included in Type 1 fonts
-% available for typesetting. This is effectively the characters in Adobe
-% Standard Encoding + ISO Latin 1 + extra characters from Lucida.
-% 
-% Character code assignments were made as follows:
-% 
-% (1) the Windows ANSI characters are almost all in their Windows ANSI
-% positions, because some Windows users cannot easily reencode the
-% fonts, and it makes no difference on other systems. The only Windows
-% ANSI characters not available are those that make no sense for
-% typesetting -- rubout (127 decimal), nobreakspace (160), softhyphen
-% (173). quotesingle and grave are moved just because it's such an
-% irritation not having them in TeX positions.
-% 
-% (2) Remaining characters are assigned arbitrarily to the lower part
-% of the range, avoiding 0, 10 and 13 in case we meet dumb software.
-% 
-% (3) Y&Y Lucida Bright includes some extra text characters; in the
-% hopes that other PostScript fonts, perhaps created for public
-% consumption, will include them, they are included starting at 0x12.
-% 
-% (4) Remaining positions left undefined are for use in (hopefully)
-% upward-compatible revisions, if someday more characters are generally
-% available.
-% 
-% (5) hyphen appears twice for compatibility with both 
-% ASCII and Windows.
