i am currently working on back-translation in liblouisutdml. We will eeventually have the capability of producinng PEF. I'm wondering if we will be back-translating it or whether back-translation will be confined to ASCII braille. What do you think? I hope VewwPlus has an opinion. John B. -- John J.
