Just type ∀ and ∃.
Obviously, for this to work you need to have mapped them to some key on
your keyboard layout.
I have them on greek-braceleft and greek-braceright in ~/.xmodmap
keycode 34 = bracketleft braceleft guillemotleft 0x1002200
keycode 35 = bracketright braceright guillemotright 0x1002203
The trick here is that X11 doesn't define symbols for those characters
so we need to enter the unicode cdes.
If you don't do that, you can enter them with C-x 8 RET THERE EXISTS RET
and C-x 8 RET FOR ALL RET

Yes.

As long as you use unicode in the whole processing chain.
