Function unicode_skeleton::confusable

pub fn confusable<A, B, AI, BI>(a: A, b: B) -> bool where
    A: UnicodeSkeleton<AI>,
    B: UnicodeSkeleton<BI>,
    AI: Iterator<Item = char>,
    BI: Iterator<Item = char>, 

Test if two strings have the same "skeleton", and thus could be visually confused for each another.
