Sorry to be late on this very long thread, but you guys are making lives difficult for yourselves by getting hold of the wrong end of the stick. There is no need to give tesseract a convoluted re-encoding of the recognizable units that you want it to recognize, and and translate it on output. Maybe I misunderstand what you were trying to do to start with, but you can give tesseract any utf-8 string for each recognizable unit that you train it with, including multiple unicodes if you want. If your original shapes/recognizable units/aksharas/syllables (call them what you like) represent multiple unicodes, then give tesseract all the utf8 for those, and it will be happy. (It currently supports up to 24 bytes of utf-8 for each shape.) It will make life easier when you want to give it a dictionary to use with the shapes, as it assumes that the words you give it can be made up of sequences of the codes for the basic shapes.
