Encodings are related to storage and transportation -- not business logic. You should not have to deal with encodings inside your application, so forcing programmers to deal with encodings at the point it matters, when text enters and exits the application, is thus sound.
If yoy truly don't care whether or not the text is decodable (which is sometimes the case), then don't read it as a string, read it as a byte array.
You can still have methods that are generic over byte arrays and text, since that is an orthogonal concern.
