Is there a way to fix the code point too high problem in Perl Tk?

The following code demonstrates my problem. Running it gives me the error message that reads:"UCS-2LE:code point "\x{20541}" too high at C:/Perl/site/lib/Tk/Widget.pm line 205. at E:\test.pl line 9".

my Tk version is 804.028 and I'm running ActivePerl 10.0.0 on WinXP (Simplified Chinese version).

Does anyone know if there's a way around it? Thanks like always :)
