ABBYY PDF Transformer 2.0
extracts textual data from a PDF document and uses these data to support the
conversion process.
If a PDF document contains special characters or non-standard fonts, the
corresponding text fragments may be displayed incorrectly in the output document
(e.g. some letters may be replaced with "?" or
"□").
To improve conversion quality, try selecting the Process PDF as image
option and converting the PDF document anew.
In this case, ABBYY PDF Transformer 2.0 will use an Optical Character
Recognition (OCR) technology, which can handle any type of PDF file
(including image-only PDF files) containing any kinds of font. ABBYY PDF Transformer 2.0
will analyze the
page as if it were a snapshot
of a document and use its OCR capabilities to recognize the text.
