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 <email@example.com>. How to Use Include ucdn.c, ucdn.h and ucdn_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 ucdn_db.h.
