@skull-squadron thanks!

This crate was selected despite it's archived status. I don't know of an alternative, and there are some unsafe in the crate, which means we can't inline the code.

The only unsafe parts are calls to str::from_utf8_unchecked (which are equivalent to transmute) for [u8] to str conversions for duplicated functionality of already known valid utf-8. The easiest thing to silence this warning might be to fork the crate because there isn't much to it and little need for constant churn/maintenance on such a trivial crate. Also, there are similar efforts of accelerating utf-8 decoding using SIMD (via assembly) for various platforms.

I asked the owner of the utf-8 crate about unarchiving it in any form. They were not open to the idea. The way forward is probably to fork and publish under a new name. There is however no sense of urgency, so we can park this question for now. See if this issue gathers more interest.
