On Unix may be any sequence of bytes except slash b'/' and zeroī'\0': > open(bytes(range(0x100)).translate(None, b'\0/'), 'w').close() Ls command may produce output that can't be interpreted as text. To interpret a byte sequence as a text, you have to know theĬorresponding character encoding: unicode_text = code(character_encoding) Lines.append(code('utf-8', 'slashescape')) #print err, dir(err), err.start, err.end, err.objectĬodecs.register_error('slashescape', slashescape) returnĪ tuple with a replacement for the unencodable part of the inputĪnd a position where encoding should continue""" It should be slower than the cp437 solution, but it should produce identical results on every Python version. UPDATE 20170119: I decided to implement slash escaping decode that works for both Python 2 and Python 3. See Python’s Unicode Support for details. Lines.append(code('utf-8', 'backslashreplace')) That works only for Python 3, so even with this workaround you will still get inconsistent output from different Python versions: PY3K = sys.version_info >= (3, 0) UPDATE 20170116: Thanks to comment by Nearoo - there is also a possibility to slash escape all unknown bytes with backslashreplace error handler. UPDATE 20150604: There are rumors that Python 3 has the surrogateescape error strategy for encoding stuff into binary data without data loss and crashes, but it needs conversion tests, -> ->, to validate both performance and reliability. See the missing points in Codepage Layout - it is where Python chokes with infamous ordinal not in range. The same applies to latin-1, which was popular (the default?) for Python 2. UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 2: invalid In no case it should not be confused with “encryption” and “decryption” which are used to protect data, while Base64 doesn’t offer any protection.If you don't know the encoding, then to read binary input into string in Python 3 and Python 2 compatible way, use the ancient MS-DOS CP437 encoding: PY3K = sys.version_info >= (3, 0)īecause encoding is unknown, expect non-English symbols to translate to characters of cp437 (English characters are not translated, because they match in most single byte encodings and UTF-8).ĭecoding arbitrary binary input to UTF-8 is unsafe, because you may get this: > b'\x00\x01\xffsd'.decode('utf-8') And since we are talking about terms, remember that the conversation of text to Base64 is called “encoding” and the reverse process is called “decoding”. However, from a technical point of view, this process is called “conversation”, therefore, never call it a “Base64 translator”. Well, by and large, it really “translates” the text into another form. It may seem funny, but some people call the “Base64 converter” a “Base64 translator”. Nevertheless, if you’re missing some Base64 encoding or decoding features, please let me know. I hope that I managed to develop all the necessary converters that meet your needs. They are also simple and free, but they are sharpened for certain tasks. If so, please check the following online convertors. Perhaps this option does not suit your needs, and you want to encode text or decode Base64 using other variations of this algorithm. Please note that this Base64 converter supports only “main standard” and decodes the data in strict mode.
