though properties of regexp under Linux is OK,ruby under windows doesn’t  
support that.  
such as /\p{Han}/,  
you will always get an error.

irb(main):001:0\> /\p{Han}/  
SyntaxError: (irb):1: invalid character property name {Han}: /\p{Han}/  
from C:/Ruby192/bin/irb:12:in `’

will anyone explain this?

i use ruby 1.9.2p0 (2010-08-18) [i386-mingw32]

That seems a bug.

Ruby Regexp is bundled by Ruby, not depending on 3rd party libraries  
that could have affected it’s compilation

If no other answer shows up that explain this, please create a bug  
report in Ruby Redmine installation:

And provide enough information about your setup, specially if you  
compiled Ruby or downloaded binaries.
