Non-Standard Encoding

Most source files use standard character encoding, but some use an internal file-specific solution. PDF Professional needs to use OCR to convert such files.

To extract text using the built-in Optical Character Recognition (OCR), select the Recognize non-standard encoded pages checkbox under Processing Options that appears on all the four processing panels (Standard Document, Legal, Spreadsheet and Form). The default value is “enabled”. For details, see Standard Document.
