    ??? I'm probably missing something: what other characters would be
    changed by using standard-case-table?  AFAIK, it is set up to change
    case only for letters from A to Z; see casetab.c:init_casetab_once.
    The letters A to Z appear in many Latin-x character sets, so A to Z
    does not imply US ASCII.

During normal execution, standard-case-table handles all the alphabets
that have a case distinction.  If ascii-case-table is a copy made
after standard-case-table is initialized, it will handle them all too.
