So (as also pointed by Edward):

- Some people are aware that decodeUtf8 is partial and rely on that behaviour
- Some people aren’t aware, and think that decodeUtf8 is like `decodeUtf8With lenientDecode` or `decodeUtf8With ignore`.

Then if we add a {-# DEPRECATED #-} warning on `decodeUtf8`, we should add variants for both use cases

lenientDecodeUtf8 which is total, and
unsafeDecodeUtf8 or strictDecodeUtf8, which is what decodeUtf8 does today.

I’d like the new names, for convenience, `OnDecodeError` values would require a new module import.
