More and more pages in unicode. Remember those times where you open a web page full of question marks? This just shouldn’t happen. Hopefully everyone moves to unicode soon. Lots of Chinese websites are still not on unicode actually.
Moving to Unicode 5.1
Just last December there was an interesting milestone on the web.

What’s more impressive than simply overtaking them is the speed with which this happened; take a look at the blue line in this graph. (Source: Google blog)
