    [PA] I also think that implementing such warning for mixed-script URL
    (IDN) would help simplify the spoofing problem and limit the confusable
    character list anyone would maintain : only the confusable characters
    within a script (and the generic characters such as basic a-z Latin,
    digest and ponctuation) would have to be considered, not all characters
    looking like a V and E across all scripts for example (Tifinagh is a new
    one for example).
