PDF Document showing difference in rendering while justified
Whenever some Arabic/Urdu text is in 'Noto Nastaliq Urdu' font and text alignment is justified, text does not render correctly in LibreOffice. LibreOffice apparently tries justify text using Tatweel characters which causes the shapes to be broken. A sample pdf file is attached which contains right aligned and justified text and rendering difference. This problem occurs in all LibreOffice versions.
Thank you for reporting the bug. Please attach a sample document, as this makes it easier for us to verify the bug.

Test Document containing text and embedded 'Noto Nastaliq Urdu' font
We do not currently have a way to disable Kashida justification and force using spaces only for Arabic text, which is breaking this font.
This probably requires both UX input (who would this be handled? in MS Office the full justification button has a menu this shows three levels of justification), and whether ODT format supports such control (OOXML probably does).
