gencfu

GENCFU(1)							 ICU 50.1.2 Manual							 GENCFU(1)

NAME

       gencfu - Generates Unicode Confusable data files

SYNOPSIS

       gencfu  [  -h, -?, --help ] [ -V, --version ] [ -c, --copyright ] [ -v, --verbose ] [ -d, --destdir destination ] [ -i, --icudatadir direc-
       tory ] -r, --rules rule-file -w, --wsrules whole-script-rule-file -o, --out output-file

DESCRIPTION

       gencfu reads confusable character definitions in the input file, which are plain text files containing confusable character definitions	in
       the  input format defined by Unicode UAX39 for the files confusables.txt and confusablesWholeScript.txt.  This source (.txt) format is also
       accepted by ICU spoof detectors.  The files must be encoded in utf-8 format, with or without a BOM.  Normally the output data file has  the
       .cfu extension.

OPTIONS

       -h, -?, --help
	      Print help about usage and exit.

       -V, --version
	      Print the version of gencfu and exit.

       -c, --copyright
	      Embeds the standard ICU copyright into the output-file.

       -v, --verbose
	      Display extra informative messages during execution.

       -d, --destdir destination
	      Set the destination directory of the output-file to destination.

       -i, --icudatadir directory
	      Look  for  any necessary ICU data files in directory.  For example, the file pnames.icu must be located when ICU's data is not built
	      as a shared library.  The default ICU data directory is specified by the environment variable ICU_DATA.  Most configurations of  ICU
	      do not require this argument.

       -r, --rules rule-file
	      The source file to read.

       -w, --wsrules whole-script-rule-file
	      The whole script source file to read.

       -o, --out output-file
	      The output data file to write.
