This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. ** This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. Is anybody going to do something about this? I have found also another issue in highlighting. So seems like that this topic is very problematic.

If you would like it considered as an exception in the current release, please ask your support representative. These are actually 2 bugs. The first one is that selection of TextLine shouldn't take y coordinates of the selection rectangle into account once we decide to select the line. We can fix this since the patch is quite simple (see http://cgit.freedesktop.org/poppler/poppler/commit/?id=5056e33e01ce0f7db1a5401b7b38d30e84eedf69). The second one is that each TextWord has only one font set which means that if a TextWord contains a character which needs different font then the character is drawn by wrong font which usually doesn't have a glyph for the character resulting in empty space. This is not possible to fix without API change since the API of TextWord is public (see http://cgit.freedesktop.org/poppler/poppler/commit/?id=f3a1b765bd6a58d327a80feedbe30e1c0792076e). I'm giving devel_ack+ to the first problem. We can not fix the second one because of the API change. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
