Should another suffix be placed behind the text or do something else?
The Vazir font doesn't support those characters, so, you need to use a font that supports those characters. you may need to change the font to Fira-Code or something that you are already using in your VS-Code.
To find out which font is already being used in your vs-code, open settings in your vs-code, type in font, and look for the font family.
then search the internet, download that font, and load that font instead of Vazir.
