encodeutils¶

oslo_utils.encodeutils.exception_to_unicode(exc)¶

Get the message of an exception as a Unicode string.

On Python 3, the exception message is always a Unicode string. On Python 2, the exception message is a bytes string most of the time.

If the exception message is a bytes strings, try to decode it from UTF-8 (superset of ASCII), from the locale encoding, or fallback to decoding it from ISO-8859-1 (which never fails).

New in version 1.6.

oslo_utils.encodeutils.safe_decode(text, incoming=None, errors='strict')¶

Decodes incoming text/bytes string using incoming if they’re not

already unicode.

Parameters:	incoming – Text’s current encoding errors – Errors handling policy. See here for valid values http://docs.python.org/2/library/codecs.html
Returns:	text or a unicode incoming encoded representation of it.
Raises:	TypeError – If text is not an instance of str

oslo_utils.encodeutils.safe_encode(text, incoming=None, encoding='utf-8', errors='strict')¶

Encodes incoming text/bytes string using encoding.

If incoming is not specified, text is expected to be encoded with current python’s default encoding. (sys.getdefaultencoding)

Parameters:	incoming – Text’s current encoding encoding – Expected encoding for text (Default UTF-8) errors – Errors handling policy. See here for valid values http://docs.python.org/2/library/codecs.html
Returns:	text or a bytestring encoding encoded representation of it.
Raises:	TypeError – If text is not an instance of str

See also to_utf8() function which is simpler and don’t depend on the locale encoding.

oslo_utils.encodeutils.to_utf8(text)¶

Encode Unicode to UTF-8, return bytes unchanged.

Raise TypeError if text is not a bytes string or a Unicode string.

New in version 3.5.
