And the answer would appear to be "yes." Or was that „sǝʎ„ ?
I'm trying to think of a compelling reason to make one's text appear upside down. I suppose that it could be amusing for about a second and then it would get irritating.
I thought maybe that upside down could be used for satirical purposes, but I think I'd need to be Ursula Le Guin before a publisher would even think about printing my story with upside-down bits. And in any case, the point of writing is to use the words, not the typesetting, to convey ideas.
Still. ǝpısdn down text is kind of cool.
