This invisible text is meant for in= teractive search and was generated using OCR but is not part of the text co= ntent of this PDF. We could look at using such text - if it exists - as a f= allback if, and only if, there is no text to extract, but strictly speaking= this PDF has no extractable text (according to the PDF spec). If we do this I would suggest that it doesn't become a part of the 'core' t= ext extraction but should be implemented as a utility/application as this i= s more application oriented. [~aputnik] You've written in the other issue that you are using OCR as a fa= llback. Which tool are you using for that?=20 > 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 > Priority: Major > Attachments: Testdokument.pdf > > > I'm using Tika (v1.18 , which means pdfbox=C2=A02.0.9) to extract the tex= t 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=C2=A0"WARNING: No Unicode mapping for ... in font ArialM= T"=C2=A0pdfbox 2.0.9 doesn't return anything. > As you can see from the warning, the font in question is ArialMT.
