X Version 11                                     font-util 1.4.1                                  bdftruncate(1)

bdftruncate  allows  one  to  generate  from an ISO10646-1 encoded BDF font other ISO10646-1 BDF fonts in
       which all characters above a threshold code value are stored unencoded.  This is often desirable  because
       the Xlib API and X11 protocol data structures used for representing font metric information are extremely
       inefficient when handling sparsely populated fonts.

       The command
              bdftruncate 0x3200 < 6x13.bdf > 6x13t.bdf
       will  generate  the file 6x13t.bdf in which all glyphs with codes >= 0x3200 will only be stored unencoded
       (i.e., they are encoded at codepoint -1).
