I would have preferred if we didn’t expose conversions between bytes and Unicode through generic conversion traits that do not make the choice of character encoding visible. However since we already have that same conversion the other way around, at this point that’s not a reason not to add this one.

Still, please expand the doc-comment to discuss encodings like https://doc.rust-lang.org/std/primitive.char.html#impl-From%3Cu8%3E does. In fact that can be mostly copy-pasted, with things like "encode" instead of "decode".

Also please have the docs on the impl rather than only the method. Some rustdoc views fold/hide the latter.
