Granted, but that's "ground", not "figure".

Composing and decomposing are purely character operations.

The spec for this makes no mention of UTF-8. All you need are
Unicode characters.

If you just want to take a Perl string and get a new string in which
each "character" is just a number representing a byte of the UTF-16
representation,
foreach (split /.*/, $str) {
if ($_ < 0x10000) {
$out .= ($_ >> 8) . ($_ & 0xff);
} elsif ...
}
What requires reaching into the guts of the representation?
