test result with "===" and "<=>"

SUMMARY
The font ligature is not rendered in terminal text. However, in the font setting window it can be displayed correctly.
The font testing is 'Caskaydia Cove Nerd Font', a variant of 'Cascadia Code'. 
(Available at here: https://github.com/ryanoasis/nerd-fonts/releases/download/v2.2.2/CascadiaCode.zip )


STEPS TO REPRODUCE
1. Open Konsole
2. Type some symbols in the command line which should display with ligature (e.g. "===" or "<=>")
3. Type the same symbols at the preview textbox in font-setting dialogue.

OBSERVED RESULT
The ligature does not work in Konsole command line, but works in preview.
