NAME
     unifuzz - Emit strings designed to test Unicode handling

SYNOPSIS
     unifuzz ([option flags])

DESCRIPTION
     unifuzz  emits strings designed to test the ability of programs intended to
     accept Unicode input to handle unexpected input. These include:  characters
     from  all	Unicode  ranges,  Private  Use characters, surrogates, undefined
     characters, non-characters, control characters,  exotic  space  characters,
     sequences	violating normalization rules, unexpected sequences (e.g. a base
     character from one range followed by a  combining	character  from  another
     range),  and  long sequences of combining characters.  It can also generate
     very long lines, strings containing embedded nulls, and ill-formed UTF-8.

COMMAND LINE FLAGS
     -b     Restrict the output to the Basic Multilingual Plane (Plane 0).

     -g     Do not emit specific characters.

     -h     Print usage information.

     -l     Emit very long lines.

     -n     Emit string with embedded nulls.

     -q     Be quiet. Omit commentary.

     -r <number>
	    Set the number of random characters to emit.

     -S     Scan ranges - emit a character from each range.

     -s <seed>
	    Set the seed for the random number generator.

     -u     Emit ill-formed UTF-8.

     -v     Print version information.

     The sequence of random characters is determined by  a  pseudorandom  number
     generator,  so the same sequence can be obtained by setting the seed to the
     same value. If not set on the command line, a seed is chosen based  on  the
     time of execution. The seed used is included in the output in a line of the
     form  "Seed  = NNNNNN" immediately preceding the random character sequence.
     Note that in order to obtain the same sequence it is necessary to keep  the
     same setting for restriction of output to the BMP.
