Dear uva, you try so hard to solve your problem of reading filenames with unicode characters in Windows, but I'm convinced this module here is going to be a "red herring" for you. I take pity you.
However, since you are here for over a month now, you should already know how to find your way around the Perlmonks website. Do go to and read Writing, Installing, and Using Perl Modules in the Tutorial section, especially A guide to installing modules for Win32.
But, if there's no way to install Lingua::ZH::HanDetect via PPM, consider ditching your Perl distribution in favour of CamelPack, which comes with a real working make, C compiler and CPAN, and is able to install quite a lot modules which lesser distributions cannot.
c:\> cpan
cpan> install Lingua::ZH::HanDetect
...........
cpan> quit
c:\> perl -MLingua::ZH::HanDetect -e"1"
