31 * This utility allows you to generate from an ISO10646-1 encoded
32 * BDF font other BDF fonts in any possible encoding. This way, you can
33 * derive from a single ISO10646-1 master font a whole set of 8-bit
34 * fonts in all ISO 8859 and various other encodings. (Hopefully
35 * a future XFree86 release will have a similar facility built into
36 * the server, which can reencode ISO10646-1 on the fly, because
37 * storing the same fonts in many different encodings is clearly
38 * a waste of storage capacity).
