Description Farid 2020-11-13 19:23:48 UTC

Description:
In the attached document, the first right-to-left paragraph with Persian alphabet and footnotes is fully justified. When the document is opened freshly, the justification is messed up and the lines of text undershoot or overshoot the content area boundary (see the screenshot). The paragraph renders flawlessly when we start editing e.g. insert a new paragraph with Enter.

The second paragraph with the same content but without the footnotes is just fine.


Steps to Reproduce:
Open the attached document. Press enter to insert a new paragraph so to fix the justification

Actual Results:
Open the attached document.

Expected Results:
The first paragraph should be fully justified like the second one.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
justify the first paragraph properly

Writer document exhibiting the bug

Uploaded a version of the document in which the font is manually set to Liberation Sans Serif ; as the original document may be rendered in Liberation serif - that's what happened for me - in which case you don't see the bug: https://i.imgur.com/Jrf1s00.png .

character rendering problem even with Liberation Sans font

Comment 6 Farid 2021-02-27 05:24:35 UTC

I don't have "Liberation Sans Serif" on my system but I get your same result (in the screenshot) with "Liberation Sans" font on Debian. However, even though the justification seems alright, some characters are misrepresented (new attached image). If you enter to insert a new paragraph they render alright.

By the way, I tried other Farsi fonts (other than Liberation Sans) and I get the same justification glitch.

thanks

Document exhibiting the bug with LibreOffice Sans font

With this document, the bug is manifested differently: A bunch of extra space appears near the 1 and the parenthesis to its right. If you press Enter and Backspace, the extra space disappears and the first paragraph becomes identical to the second.

See screenshot in attachment #170100 [details].

Tested with:
