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

i tried clciking the link with BOM but it wont load

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.

    Thanks i can see the 1st 3 bytes if BOM is used. Still the link is disfunctional and i dont know why BOM is used.

    i try using 
    #!
#!/usr/bin/perl -w

    [download]
    and 
    #!/usr/bin/perl -w
use utf8;

    [download]
    and save my script with the use of Notepad++ with utf8 encoding, but when i upload it wont run. why?

    Also in my scripts aprt from the perl syntax i use greek characatets. does that mean that i have to save my scripts in utf8 encoding or ansi? What iam trying to say here is based on what criteria should i choose as to what encoding i must pick for saving my perl scripts? Why ut8? why utf8 without Bom? why ansi? is there a reason? Why locally all encodings work and remotely only ansi does?

      No. Like i already said, your end is what's dysfunctional. There's a whole web out there to google, so no excuse.

      Also in my scripts aprt from the perl syntax i use greek characatets. does that mean that i have to save my scripts in utf8 encoding or ansi?

      ANSI is not a specific encoding. It's Windows terminology to use the local encoding, for some definition of local.

      But it's moot. Unless you use the broken/weird use encoding, Perl only understands iso-8859-1 (use utf8; off) and UTF-8 (use utf8; on).

      iso-8859-1 doesn't support greek characters, so that leaves UTF-8.

      why utf8 without Bom?

      U+FEFF is only a BOM if it's the very first character of a file. (It's a zero-width no-break space elsewhere.)

      #! is only a shebang if it's the very first characters of a file.

      That means you can only use one or the other.
