What if we allow the contraction table to define "alkways \uFFFD ..."?
So if the contraction table has no definition for \uFFFD only then will
it look in the text-table?
To me, the question mark is only a problem in 6dot contracted german
braille.  So this is the place where I'd actually want to
override it.  For normal german computer braille (8-dots) its
fine to use a question mark methinks.

Just to explan, 1456 in german 6-dot braille is the ch-contraction,
which is also allowed at word-ending.  So the en_CA representation
might be good for german 8-dot braille (I never checked) but it is
definitely confusing for a 6-dot reader.
