Are there any users of the UK, French or Marburg math codes on this list? Work on UK maths continues. I have made up a table of single-cell character definitions based mostly on the ANSI character-dot mappings. The table of mathematically significant Unicode characters developed for Nemeth is being reused, though of course the dot patterns for the symbols are being changed. The ukmaths.ctb table includes first the table of single-cell definitions, then the Unicode table. It then uses the new exactdots opcode to define dot patterns which indicate the layout of mathematical expressions. These dot patterns are also used in the ukmathi.sem file. The work is far from complete. After it is finished I will rewrite the documentation on implementing math codes. Many new features have been added to liblouis and much has been, and is being, learned from experience.
