This was exactly the case that got me into Rust; I had something that needed to be fast and needed to be callable from a variety of languages & environments (from python, C and Java immediately, and expecting to add swift later) but it also had to do a lot of unicode string handling, and I just _really_ didn't want to do it in C. After making sure that everything I needed was possible, I did it in Rust and it was an absolute pleasure; I haven't looked back.
