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/59.1/. 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.
