Those are missing font blocks, maybe try to verify your UE4 installation? Also did you change anything is system fonts?

Thanx for replying,
I tried to verify it and nothing is changed, i didn’t change any thing in system fonts, these symbols
appeared on the first usage. Is there any way to overrid these symbols manually?!

this solution might help , in editor preferences there is an option called region & language just change editor locale to English and it shall be fixed.
