NAME
unihist - Generate a histogram of the characters in a Unicode file
SYNOPSIS
unihist ([option flags])
DESCRIPTION
unihist generates a histogram of the characters in its input, which
must be encoded in UTF-8 Unicode. By default, for each character it
prints the frequency of the character as a percentage of the total, the
absolute number of tokens in the input, the UTF-32 code in
hexadecimal, and, if the character is displayable, the glyph itself as
UTF-8 Unicode. Command line flags allow unwanted information to be
suppressed. In particular, note that by suppressing the percentages
and counts it is possible to generate a list of the unique characters
in the input.
Output is produced ordered by character code. To sort it in descending
order of frequency, pipe the output into the command:
sort -k1 -n -r
By default, unihist handles all of Unicode. To reduce memory usage and
increase speed, it may be compiled so as to handle only the Basic
Multilingual Plane (plane 0) by defining BMPONLY.
COMMAND LINE FLAGS
-c Suppress printing of counts and percentages.
-g Suppress printing of glyphs.
-h Print usage information.
-u Suppress printing of the Unicode code as text.
-v Print version information.
