I'm not sure that's what the original poster needs. chr(0xD6D0) means Unicode code point U+D6D0 which is the character '훐'. Whereas the poster said the bytes represented by the ASCII string 'D6D0' are the character '中' in a 'GB' encoding. I'm not very knowledgeable about Asian encodings but I'll assume that the specific encoding is GB-2312.
So the things we need to do are:
- convert the ASCII hex string into bytes
- decode the bytes from GB-2312 to Perl's internal character representation
- convert to a suitable output encoding
Here's a complete script which does all of that:
use Encode qw(decode);
my $ascii_hex = 'D6D0'; # continue for as many bytes as required
my $bytes = pack('H*', $ascii_hex);
my $character_string = decode('gb2312', $bytes);
print $character_string, "\n";
