            Description

            The paste of a selection does not contain the space which was copied from selection in a displayed PDF.
            It can be reproduced with the enclosed file:A4-RR2016-VolII-E_cover_orig.pdf
            page#:106
            selected text:Appendix 30A earth

            The paste text will be "Appendix 30Aearth"
            This copy/paste works on the other main viewer.

              The inverse problem occurs too.
              For example:
              page 658 of the enclosed document:
              Text: "Articles 13 and 14" is copied/paste and the paste text becomes "Articles 13 and 14"
              i.e double space between "and" and "14".

              It is not just a matter of copy/paste since the search in the ICE Pdf Viewer finds the text only if we add this extra space.
              E.g
              'Articles 13 and 14', 2 space between and and 14, is found page 658 although it does not really contain this extra space

              Comment [ A very unique PDF that has a text layout that we haven't seen or no one has taken notices. When creating the bounding box we always he assume box should be create with the x,y at the lower left but in the instance of this pdf the font size is negative which creates right to left layout which is then mirrored by the current gs transform. The problem with the layout is that we create the bounding box incorrectly and everything goes sideways from there.

              I've added some code to detect the negative layout and thus we create the correct bound. Everything works as expected afterwards. ]

              System property workaround the is the preferred solution.
