Is it possible to configure an OCR library for only a custom set of input characters?
<p>I'm toying with the idea of creating an Android app to identify a set of given characters [let's say just A,E,I,O,U] and nothing more, in a given image. Is there a way I make use of the existing open-sourced OCR library and configure the language/character inputs as I'd like to have it? If yes, how can I do it?</p>

<p>Your help is really appreciated.</p>
