This is a project I have been working on for a long time, and I've finally felt good enough to release 0.1.0 to put the project into the alpha stage. There's a lot to do still, but I hope the performance gains are appealing (7-33x faster NFD normalization than the next fastest open source implementation)! If you are interested in this project and want to support its development, give the repository a star or reach out via email.
