fontname: Filenames for fonts

 
 2 Filenames for fonts
 *********************
 
 In this scheme, names may consist of only the letters (monocase a-z),
 numerals (0-9), and underscore.  Having two names which differ only in
 case is undesirable, since it results in clashes on common Windows
 filesystems.
 
    Here is the basic scheme (the spaces here are merely for
 readability):
 
       S TT W [V...] [N] [E] [DD]
 
 where
 
 S
      represents the supplier of the font.
 
 TT
      represents the typeface name.
 
 W
      represents the weight.
 
 V...
      represents the variant(s), and is omitted if both it and the width
      are normal.  Many fonts have more than one variant.
 
 N
      represents the encoding, and is omitted if the encoding is
      nonstandard.  Encodings are subsumed in the section on variants
      (SeeVariants).
 
 E
      represents the width ("expansion"), and is omitted if it is normal.
 
 DD
      represents the design size (in decimal), and is omitted if the
      font is linearly scaled.  Mittelbach in `TUGboat' 13(1) proposes
      using hexadecimal or base-36 notation.  In my opinion, the
      increased range does not make up for the unreadability of the
      common sizes (e.g., 10pt fonts would have a suffix `a' (in hex),
      or `j' (in base 36)).
 
 
    We used to try to limit font names to eight characters.  This was
 never completely possible, and since DOS filesystems have become rare,
 it's no longer an issue.
 
    The weight, variants, and width are probably all best taken from the
 original name of the font, instead of trying to relate them to some
 external standard.
