Since Python 3.0, the language's str type contains Unicode characters, meaning any string created using "unicode rocks!", 'unicode rocks!', or the triple-quoted string syntax is stored as Unicode. The default encoding for Python source code is UTF-8, so you can simply include a Unicode ch...

Python 3 accepts many Unicode code points in identifiers, meaning résumé = "~/Documents/resume.pdf" is valid if this strikes your fancy. Python’s re module defaults to the re.UNICODE flag rather than re.ASCII. This means, for instance, that r"\w" matches Unicode word characters, not ...
http://www.pythonclub.org/python-basic/encode-detail这篇文章写的比较好,utf-8是unicode的一种实现方式,unicode、gbk、gb2312是编码字符集; 2.python中的中文编码问题; 2.1 .py文件中的编码 Python 默认脚本文件都是 ANSCII 编码的,当文件 中有非 ANSCII 编码范围内的字符的时候就要使用"编码指示"来修正。
encoding and errors have the same meaning as the parameters of the same name in the str() built-in function. The codec to be used is looked up using the Python codec registry. Return NULL if an exception was raised by the codec. PyObject *PyUnicode_AsEncodedString(PyObject *unicode, ...
Since Python 3.0, the language features a str type that contain Unicode characters, meaning any string created using "unicode rocks!", 'unicode rocks!, or the triple-quoted string syntax is stored as Unicode. To insert a Unicode character that is not part ASCII, e.g., any letters with ac...
Although '1⁄2' is a reasonable substitute for '½', and the micro sign is really a lowercase Greek mu, converting '4²' to '42' changes the meaning. An application could store '4²' as '42', but the normalize function knows nothing about formatting. Therefore, NFKC or NFKD m...
In some cases, you need to transcode UTF-8 or UTF-16 inputs, but you may have a truncated string, meaning that the last character might be incomplete. In such cases, we recommend trimming the end of your input so you do not encounter an error. /** * Given a valid UTF-8 string ...
Django does not decode the data of file uploads, because that data is normally treated as collections of bytes, rather than strings. Any automatic decoding there would alter the meaning of the stream of bytes.
