Some of cyrillic letters looks just like latin letters - they are
(uppercase/lowercase) e/E, x/X, a/A, o/O, p/P, c/C, small B/B, y/big y,
small H/H, small T or m/T, small M/M, small K/K, r/big r, small b/b),
so I think that it is possible to derive cyrillic language from ASCII class.

Two letters looks like mirror images of latin letters - N,R

One letter looks like number 3, another one - like mirrored N with short
line above, yet another one - like e/E with two dots above, and yet
another one - like b| (b followed by vertical line).

But 12 more letters still need to be defined (less or more) different
from latin characters...

Is there way to learn ocrad for new letters by giving it images of these
letters?

Or is there tool which helps with building 'guess for' sequences/rules on
given image?
