What unicode symbol should I use for EDIT?

I'm trying to keep a very light payload on a wordpress plugin I'm writing.

Users will be able to:

• add - +
• refresh - ⟳
• edit

I'm thinking of using the pencil glyph: ✎, but I'm not sure about it. What's a good clear way to indicate this action lets you edit things?

I'm going to be providing title tool tips as well, but I want the icon to be as clear as possible without having to draw up custom icons.
