recode_c is a test/sample app that's written in C and uses encoding_rs.

It expects encoding_rs to have been checked out to an adjacent directory.

Please see the file named COPYRIGHT.

Git, GNU Make and a version of GCC recent enough to accept -std=c11 are assumed to be already installed.

See rustup.rs. For Linux and OS X, this means:

curl https://sh.rustup.rs -sSf | sh

git clone https://github.com/hsivonen/recode_c.git

cd recode_c
make

./recode_c --help
