Showing Letter As It Should be Seen
This seems to be a problem with the packaging of debian files from libreoffice.org. The reason why I say this is because the bibisect package works throughout from 3.5beta0 - 4.2 daily from just a few days ago.
LibreOffice 18.104.22.168 release & 4.1.2 release
Steps to Reproduce:
1. Install Telugu font through Ubuntu language support
2. Add "Telugu(itrans)" keyboard layout
3. Open writer
4. Change keyboard layout to "itrans(m17n)"
5. Type the letters kaa (one at a time, no spaces)
Attached is a good file from bibisect - you can see what the letter should look like. You don't get this result (or at least I don't) with the debian package(s) listed above. Without these the usage is completely broken for Telugu language (and I suspect for all Indian languages using subletters)
Note: PPA also has this issue so
Note also: Master is fine (outside of bibisect build from just a couple days ago)
Bjoern - tricky one I think - seems related to Ubuntu packaging
I can reproduce this (I believe -- rather unsure about the intended behavior on this one) on the Ubuntu version and dont see it on the bibisect version.
But is this really a regression? As in: Is this known to work in previous LibreOffice versions packaged for Ubuntu?
Im building an Ubuntu package without system icu to see if that helps right now -- if it does, its RESOLVED/NOTOURBUG and should be filed downstream on Ubuntu against icu.
I am "relatively positive" that this is a regression. I believe I would have noticed it before but I could be wrong, so, removing "regression" I suppose as it's not confirmed. I may go back and install 3.6 something to see if it was a problem way back then.
Note also that that itrans works fine in every other application (Firefox, Thunderbird, Text Editor, Chromium, Kate)
Indeed it is now confirmed to be a regression. Just tested on 22.214.171.124 and it works as expected
So, to triage this further:
bibisect-2013-10-12 oldest and newest seem to both work as expected on Ubuntu 13.10 (note these have been compiled on Ubuntu 12.04 LTS though)
building LibreOffice as packaged for saucy, only changing --without-system-icu keep the buggy behavior in place.
Very weird that master is broken but master in bibisect package is working
Tested an upstream build of libreoffice-4-1, which is also broken.
It is fixed in the latest build and wasnt yet broken in the first build, so this is not an "Ubuntu only"-bug, it is a upstream bug:

Thus this was broken in this range:
Of which bff8fa97e16f0f06fddc5545ea36c8bd2b18a580 looks immediately suspicious.
As this luckily is fixed on master, it should be reverse bibisectable, will do that now ...

Thus the fix should be in:
Given the author and description, 46c4e2463d517a7e4f74ee1759d837c799140fc7 "Drop the trailing white space crack" sounds like a likely candidate ...
Hmm, the cherrypick is nontrivial and I have no domain knowledge, thus CCing Khaled and Norbert. Could you guys have a look?
46c4e2463d517a7e4f74ee1759d837c799140fc7 is a Mac-specific (Core Text even) change, so it can’t be it.
Can I have the exact Unicode string and the font used?

Whops, indeed. Cherry-picking 3b4d361c21a1289b664cbcb9c15751d99ef6348d and b5bd2d1d8d09a44af354584ff187d9e935ffd973 onto the libreoffice-4-1 branch into the blind seems to fix this though. Still not sure which commit broke this, not that it matters much.
Caolan McNamara committed a patch related to this issue.
It has been pushed to "libreoffice-4-1":
fdo#70741 fdo#66042 rhbz#968892: force render full grapheme with fallback font
It will be available in LibreOffice 4.1.4.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
