Is says: "The purpose of training is not to teach the program to read characters from non-supported languages or alphabets."
I don't agree - it really needs improving up to FineReader level :)
Well, at least a few unsupported characters should be allowed to be trained like the following found in many english dictionaries: æðŋθəɡʃʌʒʤˈˌː■□
Also OmniPage is missing the dual pages detection option.
