And black cells with notches to accommodate the combining marks
etc. above and below from the white cells below and above.  I've seen
that in Thai crosswords.  Now, what character would we bend to
accommodate these notches?  I suspect this might be taking the encoding
of picture elements a bit too far.  What about circuit diagrams?
