[Bug-ocrad] Re: Feature request: numeric charset

[Antonio Diaz Diaz]

Hello manfred.

Yes, ocrad will have some day options like "--charset=numeric", or, for 
texts without numbers, "--charset=alphabetic". Also an user-defined 
charset will probably be implemented.

Of course, it will be implemented sooner if someone offers to sponsor 
it. ;-)


Regards,
Antonio.
