gensprep(8)			 ICU 76.1 Manual		     gensprep(8)

NAME
     gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

SYNOPSIS
     gensprep  [  -h,  -?,  --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s,
     --sourcedir source ] [ -d, --destdir destination ]

DESCRIPTION
     gensprep reads filtered RFC 3454 files and compiles their information  into
     a	binary	form.  The resulting file, <name>.icu, can then be read directly
     by ICU, or used by pkgdata(8) for incorporation into a  larger  archive  or
     library.

     The files read by gensprep are described in the FILES section.

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

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

     -c, --copyright
	    Include a copyright notice into the binary data.

     -s, --sourcedir source
	    Set the source directory to source.  The default source directory is
	    specified by the environment variable ICU_DATA.

     -d, --destdir destination
	    Set  the destination directory to destination.  The default destina-
	    tion directory is specified by the environment variable ICU_DATA.

ENVIRONMENT
     ICU_DATA  Specifies the directory containing ICU data. Defaults  to  ${pre-
	       fix}/share/icu/76.1/.   Some  tools in ICU depend on the presence
	       of the trailing slash. It is thus important to make sure that  it
	       is present if ICU_DATA is set.

FILES
     The  following  files are read by gensprep and are looked for in the source
     /misc for rfc3454_*.txt files and in source /unidata for  NormalizationCor-
     rections.txt.

     rfc3453_A_1.txt	 Contains  the	list of unassigned codepoints in Unicode
			 version 3.2.0....

     rfc3454_B_1.txt	 Contains the list of  code  points  that  are	commonly
			 mapped to nothing....

     rfc3454_B_2.txt	 Contains  the list of mappings for casefolding of  code
			 points when Normalization form NFKC is specified....

     rfc3454_C_X.txt	 Contains the list of code points  that  are  prohibited
			 for IDNA.

     NormalizationCorrections.txt
			 Contains  the	list  of code points whose normalization
			 has changed since Unicode Version 3.2.0.
