bdftruncate - generate truncated BDF font from ISO 10646-1-encoded BDF font
bdftruncate threshold < source.bdf >
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.
bdftruncate 0x3200 < 6x13.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).
