gensprep(8)                                ICU 74.2 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 destination directory is
              specified by the environment variable ICU_DATA.

ENVIRONMENT
       ICU_DATA  Specifies the directory containing ICU data. Defaults to ${prefix}/share/icu/74.2/.
                 Some tools in ICU depend on the presence of the trailing slash. It is  thus  impor‐
                 tant 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 NormalizationCorrections.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  Nor‐
                           malization 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.
