'''
Generic function which will decode whichever type is passed, if necessary.
Optionally use to_str=True to ensure strings are str types and not unicode
on Python 2.
If `strict` is True, and `keep` is False, and we fail to decode, a
UnicodeDecodeError will be raised. Passing `keep` as True allows for the
original value to silently be returned in cases where decoding fails. This
can be useful for cases where the data passed to this function is likely to
contain binary blobs, such as in the case of cp.recv.
If `normalize` is True, then unicodedata.normalize() will be used to
normalize unicode strings down to a single code point per glyph. It is
recommended not to normalize unless you know what you're doing. For
instance, if `data` contains a dictionary, it is possible that normalizing
will lead to data loss because the following two strings will normalize to
the same value:
- u'\\u044f\\u0438\\u0306\\u0446\\u0430.txt'
- u'\\u044f\\u0439\\u0446\\u0430.txt'
One good use case for normalization is in the test suite. For example, on
some platforms such as Mac OS, os.listdir() will produce the first of the
two strings above, in which "ะน" is represented as two code points (i.e. one
for the base character, and one for the breve mark). Normalizing allows for
a more reliable test case.
