9m.no – Short URLs for the Unicode Age
I got <a href="http://9m.no/𑂜൭" rel="nofollow">http://9m.no/𑂜൭</a> for my daughter's website, but I'm wondering whether this helps shrink character count when used for services like twitter.  It's not at all readable, but since it's two (I think) 4-byte unicode characters, will that URL be counted as 13 characters or 21 characters?
