Alphanumeric content type

Use this content type to allow for the full range of characters in the selected language to be recognized by the RecoStar or FineReader recognition engines. This content type includes characters with accents and diacritical marks. Examples of these characters include ä, ö, è, ñ, ç, and ê.

Different languages support different characters so if your project is not configured for these languages, extraction results may suffer.
