Do Win32::ODBC module support Chinese characters when used with MS Access?

Hello all,

I am a newbie to Perl & CGI (7 days).

I am using Perl 5.6 and using Win32::ODBC to connect to an MS Access
Database, where I do my Insert/Update/Delete.

I found that I can't correctly update a field's value to data
containing Chinese characters. The field's value become a mess after
running the SQL.

The value is submitted from an HTML form to this CGI. To verify, I
printed out the SQL statement to the output and I can see the correct
Chinese Chars been shown for the SQL statement. (Relevant codes given
below)

Then I run the sql using

$db->Sql($SQLCMD);

No errors, but the related field now contains unreadable chars.

e.g.
I tried to insert a Chi. Char having charcode = 0xA4A4
Inserted, and when I get back the value of the updated field,
the char becomes 0x3F3F, which would be a mess using ASP and Access.
And there's no linear relation between to charcodes.

Would anyone help me on this?

Thank You!

=========CODES BELOW=================
# Form-Data are put in Hash called %in. cwr contains Chinese chars.
my $value = $in{'cwr'};
my $rv = "";
if (defined($value)) {
if (length($value) > 0) {
for ($ic=0;$ic<length($value);$ic++) {
$px = unpack("c", substr($value, $ic, 1));
if ($px < 0) {
$ic++;
$py = unpack("c", substr($value, $ic, 1));
$px = $px + 256;
$py = $py + 256;
$px = $px * 256 + $py - 65536;
$rv .= pack("c", $px);
}
elsif (($px == 34) || ($px == 39)) {        #make
SQL-Compatible string
$rv .= pack("C", $px) . pack("C", $px);
}
else {
$rv .= pack("C", $px);
}
print "$px, ";
}
print "<br>[".$rv."]<br>";
$rv = "'" . $rv . "'";          #Single-Quote it
}
else {
$rv = "NULL";
}
}
else {
$rv = "NULL";
}
print $rv;                           <---OK
my $SQLCMD = "update Restaurants set ChiName = " . $rv . " where Id
= 1";
print $SQLCMD;                       <---Also OK

$db->Sql($SQLCMD);                   <---Also OK

(Get back to ASP reading the database about this data, and found the
field contains messy data)
