Word-list-compress is best used with sorted word list type files. It
is not a general purpose compression program since the resulting files
may actually increase in size.

Word-list-compress accepts up to 255 text characters in the range of
{0x21…0xFF}. If your word list requires a larger character set for
certain languages or longer length for multi-word, scientific, medical,
technical or other use, then it is recommended that you compress your
word list using prezip-bin

Word-list-compress normally exits with a return code of 0. If it
encounters an error, a message is sent to standard error output
(stderr), and word-list-compress exits with a non-zero return value.
Error messages are listed below:

(display help/usage message)
Unknown command given on the command line so word-list-compress
displays a usage message to standard error output.

Corrupt Input
This is only for the decompression command d. The input file is
of an unknown format or the input file/stream is corrupted. You
may have some valid output, but word-list-compress could not
complete the process. If the input file is a compressed
wordlist but you have no output file, then it may be a newer
prezip-bin version of compressed file, if so, try decompress‐
ing the file with prezip-bin instead.

Output Data Error
The output is full, write protected, or has an error and can no
longer be written to.
