I think the reason the Braille block is legitimate, and doesn't fall
into the codes-for-codes trap you described, is that it is a flexible
cipher rather than a fixed one. The same Braille symbol can stand for
different letters depending on which script, or even which alphabet
within the same script, it is used to represent. And then there's Grade
2 Braille, which completely breaks the "simple cipher" model.
