How can I add an html entity (e.g., →) using appendChild? When I put it in a textNode, I actually see the characters → rather than the right-arrow entity.

[AmeliaR]

you have to create an entity node

[ovigo22]

you could just add the character directly
But if you really want the entity reference, use document.createEntityReference
I'd just put the character into a text node though
