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 combin-
ing 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.
