I am not so sure that the original question was even talking about
artificially condensing and expanding fonts. But supposing that it
was, maybe we should at least be aware that real condensed and
expanded fonts generally do not even exist in the CJK world, and the
only way we can achieve any variation in width at all is artificially.

does anyone know how to fix Snow Leopard? it broke input method
switching and is causing many typing mistakes so it is very annoying
