I believe the problem is that "δ’ αρχαια" should have non-blank
*words*.  With U+2019, one gets 3.  Line-break suppressing spaces don't
help with word-breaking, because they are not treated as letters.

A clunky solution would be to have a sequence <delta,
control-joining-words, U+2019>.  However, there is no such
thing as a 'control-joining-words' if one complies with the TUS
injunction in Section 23.3, "The word joiner should be ignored in
contexts other than line breaking".  A robust, trainable spell-checker
will treat this institutionally racist injunction with the contempt it

It's interesting that the spellings "'bus" and "'phone" have died.
They would once have hit the word-boundary problems when "bus" and
"phone" were rejected.
