Tilman Hausherr updated PDFBOX-4141: ------------------------------------ Component/s: (was: Parsing) Text extraction > Suppress control characters? > ---------------------------- > > Key: PDFBOX-4141 > URL: https://issues.apache.org/jira/browse/PDFBOX-4141 > Project: PDFBox > Issue Type: Improvement > Components: Text extraction > Affects Versions: 2.0.8 > Reporter: Andreas Meier > Priority: Minor > Attachments: Mapping_default_to_adobe.csv, Test_with_MW.pdf, > Test_with_MW.txt, Test_with_MW_AdobeReader_export.txt, > Test_with_MW_linux.jpg, Test_without_MW.txt > > > At the moment pdfbox extracts all types of characters. > Therefore control characters that occur will also be extracted. > Unfortunately some of these control characters might deform text. > For example 'MESSAGE WAITING' (U+0095) [MW] > I attached some files and a screenshot how text is printed when MESSAGE > WAITING is present. > Should PDFBox handle this type of characters? Maybe suppress them in > PDFTextStripper? > I know that PDFBox works correctly in this case, a feature to turn off or > suppress special characters might produce better output than the default > Setting unless some control characters are used for any further processing!? > Feedback appreciated. > What other programs do: > a) ignore control characters (Okular PDF Viewer - KDE) > b) exchange them (Adobe Reader wrote a dot "." in place of MW) > Regards > Andreas -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
