1 Contents of this directory are derived from UCDN: 2 3 https://github.com/grigorig/ucdn 4 https://github.com/behdad/ucdn 5 6 The original README follows: 7 8 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>. 32 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. 42
