I've been having some character encoding problems with twitter's text query string parameter.
a) http://www.twitter.com/share?url=http://www.example.com&text=touché
b) http://twitter.com/share?url=http://www.example.com&text=touché
a) seems to do extra encoding and the tweet comes out wrong
b) see lack of www works fine.
These both redirect to :
http://twitter.com/intent/tweet?text=touch%C3%A9&url=http%3A%2F%2Fwww.example.com
Is there a point in using http://twitter.com/share rather than simply just: http://twitter.com/intent
