Isnt it enough that it has it in the shebang line as well '#!/usr/bin/perl' ?

What's "it"?, the "#!"? No. When I said it has to be the very first thing in the file, I meant it has to be the very first thing in the file. 

$ od -c a.pl

It's the Wikipedia page on "byte-order mark". I don't see why you couldn't load it.

When a script source is considered to be utf-8?

Either it is or it isn't. There's no "considered" about it. If you saved it using UTF-8 as the encoding, it's UTF-8. If you used another encoding, it isnt.

But yes, I meant when the source is UTF-8.

Perl will assume the source is encoded using iso-8859-1 unless use utf8; is used.
