This directory contains tools to generate the tables in
|
|
src/include/common/unicode_norm.h, used for Unicode normalization. The
|
|
generated .h file is included in the source tree, so these are normally not
|
|
needed to build PostgreSQL, only if you need to re-generate the .h file
|
|
from the Unicode data files for some reason, e.g. to update to a new version
|
|
of Unicode.
|
|
|
|
Generating unicode_norm_table.h
|
|
-------------------------------
|
|
|
|
1. Download the Unicode data file, UnicodeData.txt, from the Unicode
|
|
consortium and place it to the current directory. Run the perl script
|
|
"generate-unicode_norm_table.pl", to process it, and to generate the
|
|
"unicode_norm_table.h" file. The Makefile contains a rule to download the
|
|
data files if they don't exist.
|
|
|
|
make unicode_norm_table.h
|
|
|
|
2. Inspect the resulting header file. Once you're happy with it, copy it to
|
|
the right location.
|
|
|
|
cp unicode_norm_table.h ../../../src/include/common/
|
|
|
|
|
|

Tests
|
|
-----
|
|
|
|
The Unicode consortium publishes a comprehensive test suite for the
|
|
normalization algorithm, in a file called NormalizationTest.txt. This
|
|
directory also contains a perl script and some C code, to run our
|
|
normalization code with all the test strings in NormalizationTest.txt.
|
|
To download NormalizationTest.txt and run the tests:
|
|
|
|
make normalization-check
