gensprep(8)			ICU 76.1 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/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 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.
