It's probably not worth dwelling on. But I will get into this one, at the
risk of sounding like a major dork. This issue is already decided, so we
are only describing what already happens:

https://doc.rust-lang.org/std/string/struct.String.html#method.from_utf8_lossy

The reason the unichars document should not unreservedly recommend a
replacement character is because that's lossy.
