Easily type Unicode characters using AutoHotKey?

For example, I want to be able to type → (right arrow) using AutoHotKey's text replacement feature, and this is what my script looks like:

::|rarr::{ASC 2192}

So when I type |rarr in my text editor and hit , . <SPACE> <ENTER>, etc the text should be replaced with a →. But for some reason, I get this: É.

Usually that works for ASCII and ANSI characters. Should it be done differently with Unicode? If so, how?
