Great stuff. My parting advice is don't think it will always be 100% perfect. I hope it will but you could get a weird person name that brings 2 letters together just close enough to make Tesseract get it wrong. I would maybe do further testing against lots of test images - of course it depends on your onward promises and system dependencies - is this just a helper tool or does it need to be 100% accurate 100% of the time :) Great you got somewhere with it.
