Note you could answer that yourself by changing the:
u = u'¿Chapter?'
in the program I posted to:
u = unicode('¿Chapter?')
and seeing what happens.
The answer is they are not equivalent. The unicode literal form will make
use of the file's encoding declaration to know the correct encoding of the
source bytes, the other cannot. The other contains a bytestring. The
source file encoding declaration has no effect on bytestrings in the source,
so Python will not be able to convert the bytestring version to unicode as
it will by default attempt to use the ascii codec for the conversion, and
that will fail.
