Which fonts show the stroke order of all characters?
No fonts do, just sites with pictures or animations.


http://en.wikipedia.org/wiki/File:-bw.png#file  

Instructions: Past the address in your browser bar, then write a character between "File:" and "-bw", like this "http://en.wikipedia.org/wiki/File:你-bw.png#file". It will show you the character's stroke order, not animated, but very clear.
