But I'd just punch in the letters individually just as I would for any unusual word. Misinterpreting "and" is like how Swype used to put in "née" for "me". Look, maybe I'm not as precise as I should be, but one is a word that people use a couple of times a year, and the other a couple of times an hour.

And "Barack" isn't the most common spelling. I wouldn't expect it to know "Fillmore" either.

Shouldn't frequency of use matter? Why go to all this effort and not put some kind of weighting on its word choices?
