mented past 255; otherwise, the result of mapping is undefined and an error oc-
curs.

To support more compact representations of mappings from a range of source
character codes to a discontiguous range of destination codes, the CMaps used
for the ToUnicode entry can use the following syntax for the mappings following
a beginbfrange definition:

  n beginbfrange
  srcCode1 srcCode2 [ dstString1 dstString2 … dstStringm ]
  endbfrange

Consecutive codes starting with srcCode1 and ending with srcCode2 are mapped to
the destination strings in the array starting with dstString1 and ending with
dstStringm . The value of dstString can be a string of up to 512 bytes. The value of
m represents the number of continuous character codes in the source character
code range:
  m = srcCode2 - srcCode1 + 1
