This will require infrastructure changes, since currently the mnemonic
can only be a single character.  I'm not sure such a change (and the
difficulties it will cause, like how do you display the triplet, which
is today "UUU", on the modeline) would be justified.  We could instead
simply reuse the letters used by those ancient encodings, disregarding
the fact that they are already "in use".
