For normal text OCR works well. But automatically understanding what is what is more complex.
And actually understanding the context of what you're trying to use OCR on can work backward to determine what the text actually is, i.e. if it's a "Name" field then the probabilities of ambiguous letters may change (in the case of handwriting rec).
