> Is this necessary to correctly represent human language?

Yes! As soon as you have any invisible characters (eg. RTL or LTR marks, which are required to represent human language), you will be able to encode any data you want.

How many direction marks can we see in this hidden text?

None — it's tag characters instead, which are used to represent emojis. But there's no difference! Either you can smuggle text in Unicode, or you can't. It's quite binary, and you don't gain advantages from having "fewer ways" to smuggle text, but you certainly gain advantages from having emojis in your characterset.

		This yesman attitude is honestly unnerving. We make things worse, because they were worse! Sort of not, but were anyway. That’s an advantage, nothing to see here! Instead of praising the advantages of going insane, let us better make (or at least strive for) a charset that makes subj work in practice, not on paper.
