I code on a Macbook, and I actually use say... Option+i, e in order to get ê. That works inside Vim, too, I just found out.

Obviously not very helpful to people not on a Mac, but I don't have to go through Alt mappings at all.

The point of my comment is that with an imap on <a-j>, you can't input the character ê because it will trigger the mapping. This includes option+i, e on OS X.
