For OCR internally we use Tesseract, which can be trained for new fonts/symbols.

... but is beyond the scope of SikuliX support - visit the respective Tesseract docs/tutorial

Yes, that is all possible.

You have to look into the docs and for examples in the net.

I recommend to use the SikuliX IDE for your first trials (especially for capturing the needed images), before fiddling around with the Java level.

If you have specific questions about SikuliX features, come back here with a new question for every topic, best with your coding samples.

Can you help with this problem?
