I just tried to reproduce that butterfly effect (i mean, characters looking like a butterfly together (ƐЇ3), not the chaos-theory stuff) with Word, but instead i did reproduce some strange and chaotic behaviour rather associated with the aforementioned theory. Word decided that it won’t allow me to enter any Unicode characters like the greek epsilon (Ɛ) – now i wrote this i realised that earlier i had similar problems with its support for japanese characters. Funny is that with Notepad it works perfectly, as expected.
