I've written it for fun and because BOM is still a valid problem in l10n world. It's simple and relies only on standard libraries, so should work pretty much everywhere.
It contains simple test which you can run by:
+
make test
It's 22 times faster than similar one I've written in C#, so either C is faster at that or I've written it better:) Enjoy!
