In your example PDF the arrows are actually images.

All the DejaVu fonts have these harpoon arrows.
You can use the Special Characters dialog to insert them.

Here is an example of DejaVu Serif:

Verajja Serif is a derivative of DejaVu Serif (BitStream Vera Serif).
Basically the same font, but it's arrows are slimmer.

Vollkorn also has them.

These are all free fonts. There may be others ...

The best you can do in Math is to insert the double arrow as a symbol: ⇌ U+21CC

2 "H"_2 "O" oper ⇌ "H"_3 "O"^"+" + "OH"^"-"

I used oper to turn the double arrow into an operator.
