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/63.1/. 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.
