The table contains two lines that define Unicode Braille characters with the dot patterns for s and m. If these two lines are commented out the always opcode works. It should be an error to define the same single-cell dot pattern for two different characters. I am considering issuing an error message and rejecting the table if this happens. John -- John J.
