    It looks too much like the UTF-16 surrogate model, complete with invalid
    sequences, which is an acceptable model for a multi-code-unit character
    encoding but quite cumbersome for defining individual characters.
    What's more, allowing sequences of "three of more code points" would
    catapult this model well beyond UTF-16 in terms of complexity.
