The individual character metrics are surrounded with the lines
StartCharMetrics and EndCharMetrics and consist of a
list of keys and values separated by semicolons. The characters
are sorted (numeric ascending) by character code. Unencoded
characters follow all of the encoded ones and are distinguished by
having character code -1. Each character gets one line of description.
Standard keys are:
Cnwnber
wx width-x
w width-x width-y
Nname
B llx lIy urx ury
decimal value of default POSTSCRIPT
character code (-1 if unencoded).
Character width in x (y is 0).
Character width vector.
PoSTSCRIPT character name.
The character bounding box.
L successor ligature A ligature sequence. The current character
may join with the character
named successor to form the character
named ligature. Note that characters
may have more than one such entry.
Most western language fonts have wx entries rather than w ones.
Note that keys are one letter for brevity. Here too, the set is extensible,
with unknown entries ignored. (This leaves room for addition
of new infonnation, for example.) A future revision of this
format will have a specification for kerning information.
