entities is a simple ANSI C library for decoding
HTML entities to UTF-8. It is
testet with both GCC and clang.
It was originally developed by Christoph Gärtner.
Since entities uses CMake, building the library is fairly easy
$ git clone https://github.com/ooxi/entities.git entities
$ mkdir entities/build; cd entities/build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make && ./test-entities
If you need a debug build, specify CMAKE_BUILD_TYPE as Debug and rebuild.
