Well,when i want to use property in the regexp,ruby does complain that  
bad property,but i never find any good property it accepts.Now i have a  
question,does it support unicode property,such as \p{Han}??Or is it just  
dummy?

Just make sure your String has correct Unicode encoding.

I put together  
[http://redmine.ruby-lang.org/repositories/entry/ruby-19/doc/re.rdoc](http://redmine.ruby-lang.org/repositories/entry/ruby-19/doc/re.rdoc)  
which explains the supported properties. If you’ve got a recent build  
of 1.9, it’s accessible as `ri Regexp`.
