Do you see ≈ ?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

Do you see delta?

None of those are working for me but only your approximately is out?

Yes; both ≈ and ∞.

The approximately sign wasn't showing for me before likely because I was using my phone. On my computer it works fine.

Tried it in FF, chrome and opera.

In HTML source code, if you just put an unicode character that is how it renders. To render it correctly it should be put like this &#x1F25A0; in the source code.

The parser has a bug, it is not parsing the things inside the hide tag.

This should not render

but this will:

P.S.: No, it is not working

Hmm, but I have shown some light in where to start debugging.

Any reason why it is working in ShivamS' browser?

I think because chrome follows Google and not the prescribed standards. The developers of Chrome have realised that representing unicode characters as HTML codes should actually be needless.
