Doing some Unicode research I'm finding several different ways to generate Unicode characters:

```perl binmode(STDOUT, ":utf8");

my $thumbs_up = "";

$thumbs_up = "\x{1F44D}"; $thumbs_up = "\N{U+1F44D}"; $thumbs_up = chr(0x1F44D); $thumbs_up = pack("U", 0x1F44D);

print $thumbs_up x 2 . "\n"; ```

What is that \x syntax? I tried looking it up on Perldoc and couldn't find anything. Is the \N specific for Unicode?
