I think such questions are not a hot topic at the current state of the 
program. Sed would do a sufficient job.

The db part of gocr is written bad. I did not thought much about it. Pixel 
based algorithm will be replaced by a vector based algorithm.

my strategy is to lift up the recognition of latin chars to a acceptable 
level before adding new chars or languages.
db support for other languages is the maximum I can do at 
the moment.
