No idea about ø but æ is used (very rarely, to be fair) in French. Famously, it's used in the name Lætitia. We enjoy having characters that are important but comparatively rare, such as ù, which has a key of its own in the French keyboard even though it is used in a single word, "où" (meaning where), to differentiate it from "ou" (meaning or). I've always felt the key might as well say "où" on it :-)
