Thanks for this hint.  We will think about a solution.

  I think what you want is U+2027 HYPHENATION POINT.

Yes, this is a possibility.  However, having a document using both
U+00B7 and U+2027 is calling for trouble.  I think a better solution
is to have a kind of `header' to the word list which exactly specifies
the used hyphenation category characters, providing defaults which can
be easily overridden.  In German for example, the middle dot is just
fine, however for Catalan, a different one has to be used instead.
