UCDN - Unicode Database and Normalization

UCDN is a Unicode support library. Currently, it provides access

to basic character properties contained in the Unicode Character

Database and low-level normalization functions (pairwise canonical

composition/decomposition and compatibility decomposition). More

functionality might be provided in the future, such as additional

properties, string normalization and encoding conversion.

UCDN uses standard C89 with no particular dependencies or requirements

except for stdint.h, and can be easily integrated into existing

projects. However, it can also be used as a standalone library,

and a CMake build script is provided for this. The first motivation

behind UCDN development was to provide a standalone set of Unicode

functions for the HarfBuzz OpenType shaping library. For this purpose,

a HarfBuzz-specific wrapper is shipped along with it (hb-ucdn.h).

UCDN is published under the ISC license, please see the license header

in the C source code for more information. The makeunicodata.py script

required for parsing Unicode database files is licensed under the

PSF license, please see PYTHON-LICENSE for more information.

UCDN was written by Grigori Goronzy <greg@kinoho.net>.

How to Use

Include ucdn.c, ucdn.h and unicodedata_db.h in your project. Now,

just use the functions as documented in ucdn.h.

In some cases, it might be necessary to regenerate the Unicode

database file. The script makeunicodedata.py (Python 3.x required)

fetches the appropriate files and dumps the compressed database into

unicodedata_db.h.
