gensprep(8) ICU 55.1 Manual gensprep(8)

NAME

gensprep – compile StringPrep data from files filtered by filter‐
RFC3454.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, .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 direc‐
tory is specified by the environment variable ICU_DATA.

-d, –destdir destination
Set the destination directory to destination. The default des‐
tination directory is specified by the environment variable
ICU_DATA.

ENVIRONMENT
ICU_DATA Specifies the directory containing ICU data. Defaults to
${prefix}/share/icu/55.1/. 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 Normal‐
izationCorrections.txt.

rfc3453_A_1.txt Contains the list of unassigned codepoints in Uni‐
code 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 speci‐
fied….

rfc3454_C_X.txt Contains the list of code points that are prohib‐
ited for IDNA.

NormalizationCorrections.txt
Contains the list of code points whose normaliza‐
tion has changed since Unicode Version 3.2.0.
