Have a look at this thread: https://groups.google.com/forum/#!topic/tesseract-ocr/be4-rjvY2tQ
It's easier than it seems, you do not need per character boxes with 4.0, just one per line (that ocr-d automatically generates). If your text is already split into lines you do not have to do anything more. Unicharset and lstmf files are also created by ocr-d. Feel free to ask if you get stuck, now I have this working but it's a bumpy road (lot of assertion failed/segmentation fault if you miss something).
