      9 UCDN - Unicode Database and Normalization
     10 
     11 UCDN is a Unicode support library. Currently, it provides access
     12 to basic character properties contained in the Unicode Character
     13 Database and low-level normalization functions (pairwise canonical
     14 composition/decomposition and compatibility decomposition). More
     15 functionality might be provided in the future, such as additional
     16 properties, string normalization and encoding conversion.
     17 
     18 UCDN uses standard C89 with no particular dependencies or requirements
     19 except for stdint.h, and can be easily integrated into existing
     20 projects. However, it can also be used as a standalone library,
     21 and a CMake build script is provided for this. The first motivation
     22 behind UCDN development was to provide a standalone set of Unicode
     23 functions for the HarfBuzz OpenType shaping library. For this purpose,
     24 a HarfBuzz-specific wrapper is shipped along with it (hb-ucdn.h).
     25 
     26 UCDN is published under the ISC license, please see the license header
     27 in the C source code for more information. The makeunicodata.py script
     28 required for parsing Unicode database files is licensed under the
     29 PSF license, please see PYTHON-LICENSE for more information.
     30 
     31 UCDN was written by Grigori Goronzy <greg (a] kinoho.net>.

     33 How to Use
     34 
     35 Include ucdn.c, ucdn.h and unicodedata_db.h in your project. Now,
     36 just use the functions as documented in ucdn.h.
     37 
     38 In some cases, it might be necessary to regenerate the Unicode
     39 database file. The script makeunicodedata.py (Python 3.x required)
     40 fetches the appropriate files and dumps the compressed database into
     41 unicodedata_db.h.
