Subject [jira] [Created] (PDFBOX-4210) Unable to extract the text from a PDF ("No Unicode mapping.." warnings)
Date Tue, 08 May 2018 07:21:00 GMT
Aleksandar Putnik created PDFBOX-4210:

             Summary: Unable to extract the text from a PDF ("No Unicode mapping.." warnings)
                 Key: PDFBOX-4210
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4210
             Project: PDFBox
          Issue Type: Bug
          Components: Text extraction
    Affects Versions: 2.0.9
            Reporter: Aleksandar Putnik

I'm using Tika (v1.18 , which means pdfbox 2.0.9) to extract the text from PDF.

I have a document from which the Acrobat Reader (Adobe Acrobat Reader DC) can extract the
text (although not with a 100% precision).

Besides warnings "WARNING: No Unicode mapping for ... in font ArialMT" pdfbox 2.0.9 doesn't
return anything.

As you can see from the warning, the font in question is ArialMT. It is custom encoding and
the pdf doesn't include toUnicode mapping. Font type is CID TrueType (this info is provided
by "pdffonts")

"pdftotext" also can't extract anything but only shows an error `Syntax Error: Unknown character
collection 'Adobe-ArialMT'`

The pdf producer (used by the customer) is VintaSoft PDF .NET Plug-in v5.5.

I would like to determine whether there is a bug in pdfbox or the pdf producer has to adjust
and improve the "readability" of pdf.
