This PR defines `ByteArray.validateUTF8`, uses it to show that `ByteArray.IsValidUtf8` is decidable and redefines `String.fromUTF8` and friends to use it. The functions `String.validateUTF8` and `String.utf8DecodeChar?` are deprecated in favor of the identically named functions in the `ByteArray` namespace. |
