Unqualified except's are bad, since they hide the error from you.
If you change the code above into
        ...
    except:
        import traceback
        traceback.print_exc()
        ...

than you would have seen the traceback when running the exe:
  Traceback (most recent call last):
    File "hello.py", line 17, in Uni2Latin
    File "codecs.pyc", line 569, in open
  LookupError: unknown encoding: utf-16

This at least gives a hint: the encodings are not included.  They are
imported dynamically, so you must help py2exe, either this way, to
include all encodings:
    python setup.py py2exe -p encodings
or in this way, to only include the utf-16 and Latin-1 encodings:
    python setup.py py2exe -i encodings.utf_16,encodings.latin_1

If you prefer to avoid the command line options (which is recommended),
in your setup script you can write:

setup(...
      options = {'py2exe': {'packages': 'encodings'}},
      ...)

or

setup(...
      options = {'py2exe': {'includes': ['encodings.utf_16',
                                         'encodings.latin_1']}},
      ...)
