Silly but important Unicode question

With the rudimentary Win Vista or Win XP text editors Notepad or Wordpad,
one has amongst the "Save as... " options:

Encoding: Unicode | Unicode big endian | UTF-8  (in Notepad), or
Save as type: ... Unicode Text Document ... (in Wordpad).

Two fundamental questions, if I may -- and one subsidiary one:

1) How exactly do Notepad's UTF-8, Unicode, and Unicode Big-endian differ?
2) Which of those (if any) does Wordpad's "Unicode" correspond to?

Beyond that,

3) which of those will give the sort of file that, other factors not
precluding it, the site validator.w3.org will agree is deserving of the
following META tag (in the HEAD element)? -- :

<meta http-equiv=Content-Type content="text/html; charset=UTF-8">

I'd always assumed it was only Notepad's UTF-8 files, that both Notepad and
Wordpad could open and resave nondestructively. Now I'm starting to wonder:
will Wordpad's Unicode Text Documents work just as well?

Many thanks for your guidance! Cheers, -- tlvp
