I am not sure it helps, others will probably offer more elegant suggestions,
but if the dict is one-dimensional (i.e. it doesn't contain any other
containers or mappings - dicts, lists etc., but only strings, numbers,
you can use a simple print with a string conversion in a loop or join
the dict to a single printable string.
Python 2.7 (r27:82525, Jul 4 2010, 09:01:59) [MSC v.1500 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> d = {1: u'\u6c17\u304c\u9055\u3046', 2: u'\u6c17\u304c\u9055\u3046', 3:
>>> u'\u6c17\u304c\u9055\u3046', }
>>> for k, v in d.items(): print "%s: %s" % (k, v)
1: 気が違う
2: 気が違う
3: 気が違う
>>> for k, v in d.items(): print "%s: %s," % (k, v),
1: 気が違う, 2: 気が違う, 3: 気が違う,
>>>
>>> print "".join("%s: %s, " % (k, v) for k, v in d.iteritems())
1: 気が違う, 2: 気が違う, 3: 気が違う,
>>>
Or you can use python 3, where repr() behaves directly like you would
need (also for arbitrarily nested data structers, unlike the simple
approach above):

>>> d = {1: '\u6c17\u304c\u9055\u3046', 2: '\u6c17\u304c\u9055\u3046', 3:
>>> '\u6c17\u304c\u9055\u3046', }
>>> d
{1: '気が違う', 2: '気が違う', 3: '気が違う'}
>>>
(It might be possible to replace the sys.stdout to use str() as needed
on python 2.x too, but I am not sure if it would be worth it.)
