Typing Punjabi diacritics not registering as correct answer (despite being correct)

Typing either Punjabi letters ਫ਼ or ਫ਼ do not register as correct.

Although they look the same, the first is made using a diacritic, and the latter is a single script.

Typing either of them in roundy does not register as correct. Even copy-pasting the correct answer does not work. It happens in any typing punjabi course where ਫ਼ is in the question.
