To be clear, I should point out that I didn't mean to imply static
tabular mappings only. The mappings in a character encoding are often
more complex and algorithmic.
That doesn't make them any less precise, of course; and the core point
is that a character-mapping codec is *only* about getting between
characters and bytes, nothing else.
