Created attachment 103881 [details]
LibO 4.1.6 VS 4.3.1

1) Open attachment 103815 [details] in Word 2013 and convert to RTF, else open < https://drive.google.com/file/d/0B6qJrVIa0SAlbHNZaDRsYlVpQkU/edit?usp=sharing >
2) scroll to page 3
3) look at attached screenshot

Tested in 4.3.1. Regression that begin in 4.2.x. 4.2.5 doesnt display the TOC, while 4.2.7 displays it with the correct stlye (font name, size), except that the text is shown as hyperlinks (blue with underline).

how TOC looks in 4.2.7
Comment 2 Yousuf Philips (jay) (retired) 2014-08-03 14:34:46 UTC
Tested 4.3.1 on Windows and it looks similar to the 4.2.7 screenshot except that all the text is in Times New Roman.
Comment 3 Yousuf Philips (jay) (retired) 2014-08-03 22:29:07 UTC
Checked this issue on 4.4 on Linux and here is now it looks (basically the same as 3.2.1) - attachment 103946 [details]. Seems linux is more broken than windows on this issue, but both arent perfect.
Comment 4 Yousuf Philips (jay) (retired) 2014-08-05 09:42:07 UTC
The fixing of the font in the last few days has fixed half of the issue now. Now the only remaining issue is that 4.3.1 looks like the 4.2.7 screenshot (text is in blue with underline).
Comment 5 Joel Madero 2014-08-06 01:45:55 UTC
Bodhi Linux 2.4 running E17
LibreOffice 4.4 built August 7, 2014

New - confirmed
Normal - can prevent high quality/professional work
High - regression

Bibisect - JUST FOR FONT COLOR AND UNDERLINE (this was a separate issue than the other one that was resolved already)

commit 9679e9c23216decb5f9f25f85b04cb3f25211111
Author: Vinaya Mandke <vinaya.mandke@synerzip.com>

    fdo#69649 Fix for pre-rendered Table Of Contents
    Added Import and Export Uts for the same
    Reviewed on:
    Change-Id: I966b3d268dd407aa05823e29fe1da4d097091265

Looks somewhat suspicious as it handles TOCs, CC'ing author.
Comment 7 Miklos Vajna 2014-10-14 12:47:30 UTC
The problem is that the table of contents has a character style and also has direct character formatting. For contents inside the table of content field result, Word seems to ignore the character style and only handles direct formatting, and in case of DOCX, we do the same.

The situation is a bit more complicated for RTF, as in every RTF file Writer or Word produce, in case a character style is used, the contents of the character style is duplicated after the character style usage, to support old readers, not handling character styles. This means that on import, we have to find out what direct formatting is just a duplication of the character style and what is real direct formatting.

We do this already to help import performance, but in this case it also affects correctness. So the question is why the underlining is not detected as a duplicated direct formatting. If that's fixed, the underlining will go away from the TOC.
Comment 9 Vinaya Mandke 2014-10-16 05:26:45 UTC
Thanks for the patch !!!
