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.
