I guess the problem is with font fallback mechanism in DDE where the system chooses a font that only contains glyphs of isolated form of Perso-Arabic letters as the fallback font when system font doesn't support Perso-Arabic script.

How to create shortcut like in Windows? 
Since deepin 20.4, when the system language does not use Perso-Arabic script (English, Chinese, Japanese, etc.), all letters in Perso-Arabic script are displayed in isolated form.
As shown in the screenshot above, (1) is an example of display in title bar (Isolated), (2) is an example of display in dde-file-manager (Isolated), (3) is the correct display form.
