Which charset will be used for the POT file?  Just to be clear, my
opinion is that if an encoding is declared (either iso-8859-1 or utf-8)
but document only contains ASCII characters, the POT file should not
declare its charset being UTF-8 (ie. charset=CHARSET is unchanged).

Yes, as soon as master document contains non-ASCII characters, PO files
have to be UTF-8 encoded.
