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.
