Python needs to know the encoding of the bytestring in order to convert it
to unicode.  If you don't specify an encoding, ascii is assumed, which
doesn't work for any bytestrings that actually contain non-ASCII data.
Since you are reading the string from standard input, try using the encoding
associated with stdin:

>>> a = raw_input("text: ")
text: おはよう
>>> b = u"おはよう"
>>> import sys
>>> unicode(a,sys.stdin.encoding) == b
True
