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 se-
       quences (e.g. a base character from one range followed by  a  combining
       character  from another range), and long	sequences of combining charac-
       ters.  It can also generate very	long lines, strings containing	embed-
       ded 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 num-
       ber 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.
