libutf is a UTF-8, UTF-16, and UTF-32 decoding and encoding library for C.
It's used for taking advantage of the new char16_t and char32_t types and string literals in the C standard.
It is meant to be stable, lightweight, fast, and portable across platforms and compilers.
It conforms with RFC2279 and RFC2781, which are distributed with the source code.
It is meant to compile on a wide variety of compilers (including MSVC) and operating systems.
This is the current release plan:
| Version | Changes | Status |
|---|---|---|
| 4.1.0 | Adding string and stream objects, alternatives to FILE structure. |
In progress |
| 4.2.0 | Adding regex structures, capable of nested expressions | Not started |
| 4.3.0 | Adding parser generator that supports all UTF types | Not started |
| 4.4.0 | Adding an optimization stage to the parser generator | Not started |
On Ubuntu, you can install the project using apt-add-repository, like this:
sudo apt-add-repository ppa:taylorcholberton/libutf
sudo apt-get update
sudo apt-get install libutf
CMake is used as the primary build system, but GNU Make and NMake are also available.
To build the project using CMake, do this:
mkdir build && cd build
cmake ..
cmake --build .
ctest --verbose --output-on-failure
cmake --build . --target install
With GNU Make, do this:
make
make test
make install
Documentation is generated with Doxygen.
On Windows, the documentation is installed as HTML in a documentation directory.
On Unix, the documentation is installed as man pages.
Viewing the man pages are done like this:
man libutf-procedural
man libutf
If Doxygen is not installed during the build process, the documentation can be viewed in the header files.
