gensprep
gensprep(8) ICU 50.1.2 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 /usr/share/icu/50.1.2/. 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 Normal-
izationCorrections.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.
