There are some texts that I need to scan that include old letters and symbols which Acrobat cannot recognize. Is it possible to teach the OCR software how to interpret certain symbols? It does recognize them as separate letters, you can highlight and copy them, but it does not know what letter it corresponds to in the language you are scanning to.
Those are letters that are no longer part of the Bulgarian language, I'd like to be able to tell Acrobat to which unicode character/code I want them to correspond during recognition, so I don't have to manually replace the random weird combination of characters the software inputs in its place.
Is there such an option? Acrobat does recognise them visually as separate symbols, but it doesn't know what to do with them.
