The Repair incorrect font mappings mode reconstructs damaged or unusable mappings between PDF character codes and readable text. It processes existing PDF text and therefore differs from Recognize text in images, which extracts text from image content. The combined Recognize text and repair font mappings mode performs both processing steps.

The Deactivate CMAP option is available only for a mode that includes font-mapping repair: Repair incorrect font mappings or the combined mode. It ignores existing CMap mappings so that text reconstruction can determine a new mapping. This can help when PDF text looks correct but copies incorrectly. In the combined sidebar, Deactivate CMAP is shown when OCR text recognition is active with a selected normalization level.

Ignoring existing mappings can increase processing time and is not required for clean PDF files. Its actual visibility depends on the available OCR and font-mapping extensions.

For the combined control, see OCR-assisted processing. The technical profile property and its GUI mapping are described on the programming page.
