The following tests examine whether a user agent displays IDNs (Internationalized Domain Names) as Unicode or punycode in the status bar. User agents that try to detect possible homograph attacks do so in different ways. These tests explore some of those approaches. They are not exhaustive, and the results may change over time, since there is no standard for how to proceed in this respect, and some of the tests are based on lists that may change.
