PEP 8 says ... Files using ASCII (or UTF-8, for Python 3.0) should not have a coding cookie.
What about a BOM (Byte Order Mark)? Per Wikipedia ... http://en.wikipedia.org/wiki/Byte-order_mark#endnote_UTF-8) 'In UTF-8, this is not really a "byte order" mark. It identifies the text as UTF-8 but doesn't say anything about the byte order, because UTF-8 does not have byte order issues.' So is it good style to omit the BOM in UTF-8 for Python 3.0? -- http://mail.python.org/mailman/listinfo/python-list
