Description Muhammad 2016-08-23 14:18:14 UTC 
Caret appears in wrong location when using dynamic word wrap with Arabic text. The bug only appears in paragraphs that start with RTL text and thus have a Right-to-Left direction.


Reproducible: Always

Steps to Reproduce:
1. create a new document.
2. enable dynamic word wrap.
3. type/paste some text has has RTL direction (it needs to be long enough to wrap, or you can make the editor window smaller to force text to wrap).

Actual Results:  
You will see that the caret position is actually one letter off its correct position, selecting a single letter or a few words will show it clearly.

Expected Results:  
Caret should appear in its exact position.

The problem does not appear on the last line of a paragraph.
Paragraphs that start with English letters (paragraphs with Left-to-Right direction) do not have that problem even if they contain Arabic words or other UTF characters.

Kate version: 16.04.3 (also in KWrite 16.04.3)
OS: Manjaro 16.06.1 (x86_64)

I have the same problems (Fedora 24, Kate 16.04.3, Kwrite 16.04.3): Caret appears in wrong location when using dynamic word wrap with Arabic text

Can one of those affected please re-test on a recent version of kate and confirm if this is still an issue, thanks.

Unfortunately, the bug still persists in the latest release and nightly version of Kate on Windows.
