Most of the time, this is not a problem, because the main reason to do OCR on scanned documents is to make them searchable, which works very well even if some words are not correctly recognized. Unfortunatly, text recognition is a very hard problem and therefore the results are not always accurate. PDFScanner currently supports English, German, French, Spanish, Italian, Dutch, Portuguese, Swedish, Danish, Norwegian and Finnish. OCR works best if the language of the document is known, so the scanner settings dialog allows to select an OCR language.
