gensprep(8)                     ICU 69.1 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
              destination directory is specified by the environment variable
              ICU_DATA.

ENVIRONMENT
       ICU_DATA  Specifies the directory containing ICU data. Defaults to
                 ${prefix}/share/icu/69.1/.  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
       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 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.
