3) What is expected to happen in LibreOffice Writer via the Terminal:

cd ~/Desktop && wget -c https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/928707/+attachment/2729211/+files/ubuntu-bug-928707.odt -O example.odt && lowriter -nologo example.odt

export to PDF, open in Adobe Reader or Evince and it looks as it does in Writer.

4) What happens instead is the PDF looks mis-exported as per attached screenshot: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/928707/+attachment/2723326/+files/lmodern.png

Sébastien Maccagnoni-Munch, thank you for reporting this and helping make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:
apport-collect 928707
When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.
As well, could you please attach an example Writer file, that when exported to PDF, demonstrates this problem?

Joining the resulting PDF file.

Some characters are ok, others have the described problem. Especially "ê". I think I saw other characters with the same problem, but I don't remember which ones, ans I'm not 100% sure.

[penalvch (penalvch)]

Sébastien Maccagnoni-Munch, the issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at http://wiki.documentfoundation.org/BugReport . If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Created attachment 57098
image containing two screenshots, one of a document in LibreOffice, the other one of Evince, the Ubuntu PDF viewer, with the document exported from LibreOffice

Problem description:

When using some accentuated characters with any of the lmodern fonts in LibreOffice, printed pages and PDF exports include bogus characters. See attached image/screenshots.

Steps to reproduce:
1. Create a document using any "Latin Modern" font (for example from "lmodern" package in Ubuntu)
2. Use many accentuated characters in this document (especially "ê")
3. Export the document to PDF or print it.

Current behavior:

Some characters (especially "ê") are not correctly exported/printed.

Expected behavior:

Characters are correctly exported/printed.

This ODT file contains a text (in french) which uses accentuated characters, in different fonts.

[Sébastien Maccagnoni-Munch (tiramiseb)]

I've exported the LModern Type1 font from the Ubuntu "lmodern" package to the TrueType format (with instructions from http://www.vromans.org/johan/OOo/oofonts03.html).

When using this TTF export, the "ê" character is correctly exported to PDF and printed.

[chris (ign-christian)]

I can't reproduce that (though those fonts not installed), PDF export show same result as odt file. Perhaps it's been fixed.

LO 4.0.4.2 (Win7 32bit)
LO 3.6.6.2 (Ubuntu 12.04 32bit)

[Sébastien Maccagnoni-Munch (tiramiseb)]

I can't reproduce it either, with LibreOffice 4.0.2.2 from Ubuntu 13.04.

I've tried exporting the same ODT file to PDF with the same fonts package installed (lmodern), it works now.

Fix Released as per https://bugs.freedesktop.org/show_bug.cgi?id=46109#c6 .

[elijahbal (david-kremer-dk)]

I am astonished this has been released with the last version since this bug makes the software barely usable as it is.

Here a screenshot of what is missing (essentially é,è, à and ê UTF8 chars).

Only the Nimbus family font seems concerned as far as my testing goes.

Here a screenshot made with the 5.1.1.3 libreoffice version and the Archlinux rolling release operating system.
