apologies if this isn't the right forum to ask this question.
I saw some special characters like these here.

Sorry, I don't even know how to edit or write them. As far I understand these are too many characters for 8 bit unicode at ones and these are special characters which are taking place of just one unicode. How this all is happening. I don't seem to understand how these are generated or written or anything. I'm doubting myself, now I admit I don't know anything about Unicode at all.
