Thanks.  If there's no existing property of characters that we could
use to produce this order, I guess we will need an alist of characters
and their ordinal numbers, and use that.  Or, if the codepoints of
these characters are contiguous, we could have just the ordinal
numbers in the order of the codepoints, and use that in the function
passed as the PREDICATE argument to 'sort'.
