The problem is not fixable. See the pdfminer.six faq. Chars that can not be read should only be used as delimiters for things like #46 or similar.

The current approach actually works for some cid codes, namely those for the german umlauts.

The current approach actually works for some cid codes, namely those for the german umlauts.

I doubt we can assume this in general.

Instead, we could do the following:

  • Store the PDF BBox and the page of each cid char
  • use the original, not preprocessed, PDF to extract the glyph (image)
  • use a OCR library to detect the char from the image
  • in case that fails, give up.
