Question
: Do you have an add-on option to recognize Chinese for Omnipage 14 Pro or newer by using MS Office's language pack?
Answer : At the time of writing this, the latest version of Nuance OmniPage, OmniPage Ultimate, has the ability to recognize Chinese simplified and Chinese traditional characters.
Unfortunately, there is no way to update recognition languages using Microsoft Office language packs, as adding new OCR language capability requires more information than just a list of possible characters.
