I presume you copied a Unicode box character from a console window
(not DOS), prompting IDLE to save your file as UTF-8 and insert an
encoding declaration.

Yes, it always works. It's handled by the parser:

    >>> src = '# -*- coding: utf-8 -*-'

    >>> st = parser.suite(src)
    >>> parser.st2list(st)
    [339, [257, [0, '']], 'utf-8']
    >>> symbol.sym_name[339]
    'encoding_decl'
