Description Yousuf Philips (jay) (retired) 2017-10-02 19:44:49 UTC
steps:
1. open writer in Arabic UI
2. open the options dialog, the styles toolbar combobox, or about dialog.

regression as this doesnt happen in 5.2.7. isnt a harfbuzz regression as using the old layout engine in 5.3 didnt solve the issue.

I can reproduce this in the styles menu. My guess is it is a font fallback issue (these styles specify a font that does not support Arabic). What is your UI font in the about dialog case?

This might be a duplicate of bug 73494.

On linux, the font in the styles menu looks like Times New Roman from my tests. No idea what is being used on windows, but i'm on Windows 8.1.

The system font on Linux Mint 18 Mate is Noto Sans and on Ubuntu Mate 16.04 is Ubuntu, though the UI font looks identical in both systems, so i dont think it is using this font for the LO UI.

So all are fonts that lack Arabic support and the strings have mixed direction (e.g. numbers or English text next to the Arabic), which further suggests it is a duplicate.

The heading style names are not mixed numbers.

Look again, عنوان رئيسي ١ is broken, while عنوان فرعي is OK.

Yes you are right, i missed that you said numbers and only saw 'english text'. :D

I checked gtk3 and it doesnt have the problem in the styles menu, but has it in the styles combobox and options dialog.
