I have a form that accepts file uploads. A user is free to upload files with any names they like. Most file names will be in English, but some will have names with East Asian characters (Chinese, Korean, etc.)

I need to save these files to a Windows server. And I must keep their original names.

Is it necessary for Perl to know the language of the string? Is it possible to "sniff out" the language?

Thanks for any ideas on how to implement this. ikegami has already provided much help with this code: 

use strict;
use warnings;
use Encode         qw( encode );
use Symbol         qw( gensym );
use Win32API::File qw(
   CreateFileW 
   OsFHandleOpen
   CREATE_ALWAYS
   GENERIC_WRITE
);

my $qfn = chr(0x263a);  # Whatever

my $win32f = CreateFileW(
   encode('UCS-2le', $qfn),
   GENERIC_WRITE,             # For writing
   0,                         # Not shared
   [],                        # Security attributes
   CREATE_ALWAYS,             # Create and replace
   0,                         # Special flags
   [],                        # Permission template
)
   or die("CreateFile: $^E\n");

OsFHandleOpen( my $fh = gensym(), $win32f, 'w' )
   or die("OsFHandleOpen: $^E\n");

print $fh "Foo!\n";
