Thank you for your answer. My English is very poor, so I'm afraid I can't describe my question clear.
In the header, I write these:
use XML::Simple;
use XML::Parser;
use Data::Dumper;
use Encode;
use utf8;

Then, I wrote some Chinese Charactors in file by program and try to read it. The new charactor I input can be read correct, but charactors in program can't be shown correctly!

Perhaps encoding of program is not utf8, is it?

In addition, I prees refresh of IE, then I got three same article here. How to delete two of them?
Thanks!
