Description Hossein 2022-11-09 21:25:55 UTC
Created attachment 183509 [details]
ZWNJ is lost in the fields

Description:
Open attachment 182846 [details] from tdf#151364 which is a DOCX file containing fields that can be changed using the dropdown menu. In this document, ZWNJ is lost in the fields, and also in the dropdown menus.

Steps to Reproduce:
1- Open DOCX attachment
2- Click on a gray field in page 1
3. Click on the down arrow to open the drop down menu

Actual Results:
Item 1 in the dropdown menu is 'چندرسانهای' which is incorrect, because ZWNJ (zero-width non-joiner) is lost.
Also, in page 1 you can see 'پایاننامه' which is also incorrect.

Expected Results:
Item 1 in the dropdown menu should be 'چندرسانه‌ای'. The ZWNJ (zero-width non-joiner) separates two characters from joining each other. The other field should be 'پایان‌نامه'.


Reproducible: Always

Comment 1 Miklos Vajna 2022-11-10 08:30:04 UTC
Could you please attach a minimal reproducer that only has a single paragraph, with something like: "content control: ... sdt stuff here ..." in it?

Your description claims that U+200C is lost, but when I check the list items in the first SDT in the document (word/document.xml), then none of the list items or the sdt content have such a character. This means that of course the resulting doc model won't contain it, either.
