1 Contents of this directory are derived from UCDN: 2 3 https://github.com/grigorig/ucdn 4 5 The original README follows: 6 7 8 UCDN - Unicode Database and Normalization 9 10 UCDN is a Unicode support library. Currently, it provides access 11 to basic character properties contained in the Unicode Character 12 Database and low-level normalization functions (pairwise canonical 13 composition/decomposition and compatibility decomposition). More 14 functionality might be provided in the future, such as additional 15 properties, string normalization and encoding conversion. 16 17 UCDN uses standard C89 with no particular dependencies or requirements 18 except for stdint.h, and can be easily integrated into existing 19 projects. However, it can also be used as a standalone library, 20 and a CMake build script is provided for this. The first motivation 21 behind UCDN development was to provide a standalone set of Unicode 22 functions for the HarfBuzz OpenType shaping library. For this purpose, 23 a HarfBuzz-specific wrapper is shipped along with it (hb-ucdn.h). 24 25 UCDN is published under the ISC license, please see the license header 26 in the C source code for more information. The makeunicodata.py script 27 required for parsing Unicode database files is licensed under the 28 PSF license, please see PYTHON-LICENSE for more information. 29 30 UCDN was written by Grigori Goronzy <greg (a] kinoho.net>. 31 32 How to Use 33 34 Include ucdn.c, ucdn.h and unicodedata_db.h in your project. Now, 35 just use the functions as documented in ucdn.h. 36 37 In some cases, it might be necessary to regenerate the Unicode 38 database file. The script makeunicodedata.py (Python 3.x required) 39 fetches the appropriate files and dumps the compressed database into 40 unicodedata_db.h. 41
