gensprep(8)			ICU 51.2 Manual			   gensprep(8)

NAME
       gensprep	 -  compile  StringPrep	 data  from  files filtered by filter‐
       RFC3454.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	direc‐
	      tory is specified by the environment variable ICU_DATA.

       -d, --destdir destination
	      Set  the destination directory to destination.  The default des‐
	      tination directory is  specified	by  the	 environment  variable
	      ICU_DATA.

ENVIRONMENT
       ICU_DATA	 Specifies  the	 directory  containing	ICU  data. Defaults to
		 ${prefix}/share/icu/51.2/.  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 Normal‐
       izationCorrections.txt.

       rfc3453_A_1.txt	   Contains the list of unassigned codepoints in  Uni‐
			   code 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 speci‐
			   fied....

       rfc3454_C_X.txt	   Contains the list of code points that  are  prohib‐
			   ited for IDNA.

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