They are identical, except that the first one contains a ligature bringing the f and the i together. The second one has no ligature. The first is the standard in proper typesetting, and it is the default output of LaTeX. If I search for fire in Okular, the word will not be found, because Okular doesn't understand the ligature. By way of comparison, Adobe Reader for Linux does understand the ligature, and finds the word. This can lead to great frustration. I imagine that this applies to all documents in Okular, rather than being specific to the PDF backend. There are a handful of other common ligatures that this applies to (see http://en.wikipedia.org/wiki/Typographic_ligature).

[Bug 411538] Re: Okular can't find words with 'fi'.
Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. At least, I cannot reproduce the issue, using the example PDF comment 2. The first found 'coifig' is at the bottom of page 3. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 411538 and any other logs that are relevant for this particular issue. ** Changed in: kdegraphics (Ubuntu) Status: Triaged = Incomplete ** Also affects: kdegraphics via http://bugs.kde.org/show_bug.cgi?id=181828 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdegraphics in Ubuntu. https://bugs.launchpad.net/bugs/411538 Title: Okular can't find words with 'fi'.

[Bug 411538] Re: Okular can't find words with 'fi'.
Discovered bug while searching a PDF that had been output by LyX. This could be reasonably frustrating in very long documents. I'm fairly sure this bug was not present in kpdf on KDE 3, as I remember being able to search for words with ligatures in them when I first discovered ligatures and wanted to zoom in on a nice, PDF rendering of one. I will check to see if the bug is present in kpdf. Not knowing how these things work but having previously given it a passing thought, I had always assumed that the text in the document must be converted internally by the viewing application into plain text version without ligatures and that this version is what gets used for copying to the clipboard or searching within the document. -- Okular can't find words with 'fi'. https://bugs.launchpad.net/bugs/411538 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 411538] Re: Okular can't find words with 'fi'.
think about ligatures. i think your pdf contains them and okular doesn’t find the letters “f” and “i” in this order since there is in fact only the ligature glyph “fi”. i think should convert every search query to a regular expression searching either the ligature or the single letters: gadaffi → gada(ffi|ffi|ffi) -- Okular can't find words with 'fi'. https://bugs.launchpad.net/bugs/411538 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

i have written a python function correcting the bug. a okular developer has to port it to c++ (or whatever okular is written in) and call the method ligre on the search string before performing a regular expression search with it. included in the script is a test string which is transformed perfectly with the method. ** Attachment added: python method waiting for port to c++ http://launchpadlibrarian.net/33788059/ligatuRE.py -- Okular can't find words with 'fi'. https://bugs.launchpad.net/bugs/411538 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
