That's not actually documented on the Predicate Format String Syntax
or BNF Definition of Cocoa Predicates pages. There's something about
escape sequences for numbers, but not about string contents. I
suppose it's likely that escapes are supported for meta-characters.
I suppose some trial and error would reveal if it works. I'm not
that invested. ;)
