gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

gensprep [ -h, *-?, –help* ] [ -v, –verbose ] [ -c, –copyright ] [ *-s, *–sourcedir**/ source/ ] [ *-d, *–destdir**/ destination/ ]

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.

-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.

ICU_DATA

Specifies the directory containing ICU data. Defaults to ${prefix}/share/icu/70.1/. 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.

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.
