The default b64encode() functions uses the standard Base64 alphabet that contains characters A-Z, a-z, 0-9, +, and /.Since + and / characters are not URL and filename safe, The RFC 3548 defines another variant of Base64 encoding whose output is URL and Filename safe. The MySQL documentation on West European Character Sets 9§ 10.1.14.2) contains: Some more details can be found in the MySQL source code in the file many setups this will still ‘just work’, and the problem can go unnoticed for a a type unicode is a set of bytes that can be converted to any number of encodings, most commonly UTF-8 and latin-1 (iso8859-1) the print command has its own logic for encoding, set to sys.stdout.encoding and defaulting to UTF-8. You could either unpickle it using Python 2, or use Python 3 with the *encoding=’latin1’ in the pickle.load function. the core Python developers) need to provide some clearer guidance on how to handle text processing tasks that trigger exceptions by default in Python 3, but were previously swept under the rug by Python 2’s blithe assumption that all files are encoded in “latin-1”.

Older Python versions had a “narrow or wide” compilation option: UNIX and Mac OS X uses wide mode: the unicode type uses 32-bit code points. What makes this problem worse, is that MySQL defaults to using the latin1 If you use a more restrictive encoding – for example, latin1 (iso8859-1) – you won’t be able to store certain characters in the database, and information will be lost. When we encode Python Objects into JSON we call it a Serialization. SAS windows, wlatin-1 as a default encoding type. If you need Latin-1 encoding, you have several options to get rid of the en-dash or other code points above 255 (characters not included in Latin-1): If you aren't required to output Latin-1, then UTF-8 is a common and preferred choice. The Python equivalent would be close to what you wrote, but starts with a unicode representation to illustrate that PostgreSQL stores everything in the database encoding. CSV (Comma Separated Values) may be a simple file format accustomed to store tabular data, like a spreadsheet or database. The popular encodings being utf-8, ascii, etc. Background.

Also I don't know what is the theory behind encode('cp1252') it would be great if I can get some explanation on what I tried above. So: In Latin-1, you map the 256 possible bytes to the first 256 Unicode characters. It is recommended by the W3C and nicely encodes all Unicode code points: The unicode character u'\02013' is the "en dash". The English alphabet, numbers, and basic symbols are viewable with a system called Latin1 encoding. encoding latin1 to utf-8. I believe 2021 is not too early for this change. Windows PC.

The Python Mysql driver then decodes the data it receives using the connection encoding it set. CPython implementation detail: Some common encodings can bypass the codecs lookup machinery to improve performance. Whenever Python — or any other program — writes text to a file, it has to decide how to encode that text as a sequence of bytes. Encoding and decoding is the process of going from one to the other: The Encoding is latin1 and the PostgreSQL Version is 9.2.24. TODO: Support encoding aliases: pc437 instead of cp437.

UTF-8: It uses 1, 2, 3 or 4 bytes to encode every code point. with such databases. Parameters. MySQLdb uses the Python latin1 codec for data MySQL reports to be latin1 (though MySQLdb might have better chosen cp1252 here, I think, given MySQL clearly documents that they really mean cp1252 when they say latin1). Something like: >>> print u"Nadège".encode("latin-1").decode("utf-8") Nadège This code produces correct version Veřejné. '.encode('utf8').decode('latin1') 'On écrit ça dans un fichier.' But I am not sure what would be the solution to overcome this issue. It is contained in the Windows-1252 (cp1252) character set (with the encoding x96), but not in the Latin-1 (iso-8859-1) character set. When invoked on the command line, this script converts the dump file(s) The Python latin1 codec, however, does not assume 'unassigned' latin1 code points have their cp1252-assigned values. https://docs.python.org/3/library/sys.html.
