Hi all, I'm trying to use tesseract to recognize some text
interspersed with symbols. I've managed to train a new language as
explained in the wiki, but I find that sometimes tesseract places the
boxes incorrectly during recognition.

Are there any parameters which control the box placement?
I'd prefer user visible parameters but I don't mind hacking the code.

For example, if I have a horizontal arrow, then this is sometimes
split into three boxes like [-][-][>]. I'd like the algorithm to be
more lenient and try to recognize the full arrow as a single
character.

I've trained a few samples with the correct box size, but
it doesn't seem to help (ie tesseract still insists on splitting in
its own way). Should I train with a lot more samples?

All help appreciated.
