problem with unicode?

[tvlgiao(tm)]

Hi,
I have a problem with unicode.
In the Python Shell (Python GUI), i wrote a line:
>>> print u"trịnh vũ long giao"
 
i want to print an unicode string, but the interpreter printed an error:
Unsupported characters in input
 
does the interpreter not understand unicode chars?

my program has some unicode strings, i can not save it with Python GUI IDE.
does my python have problem?
 
i use Python 2.3.
can anybody help me?
 
thanks
tvlgiao
