Idea for improved handling:

Change the 2-pass flow (currently, recognised names then numeric codes, writing
into a Unicode[256] for initialising in CharCodeToUnicode::make8BitToUnicode) to
have a preliminary pass deciding whether to use hex or decimal, and a single
main pass which reads character names, numeric codes and ligatures, by passing
components to a small function which takes the component and "hex" bool and
writes into uBuf if successful.

This will mean initialising CharCodeToUnicode::make8BitToUnicode with an empty
Unicode[256] (because the main pass needs to use ::setMapping), but that's just
a performance hack and ::setMapping is fast for the single-character case anyway.

Hopefully the code will be clearer than the above.
