Hi! I'm working on single letters and grade 2. How are you doing this for the english tables in liblouis, e.g. why isn't the single letter word 'a' output as '56-1' according to the tables? I'm aware of the letsign and noletsign, but I cannot find these opcodes in the English tables, neither can I find lines like 'word a 1'. If choosing to use noletsign, should the characters be typed separated by comma? Lars For a description of the software and to download it go to http://www.jjb-software.com
