如 果需要一种单一的单一的表示方式,可以使用一种规范化的Unicode文本形式来减少不想要区别。Unicode标准定义了四种规范化形式: Normalization Form D (NFD),Normalization Form KD (NFKD),Normalization Form C (NFC),和Normalization Form KC (NFKC)。大约来说,NFD和NFKD将可能的字符进行分解,而NFC和NFKC将可能的...

The Unicode code point for a given character can differ from the code points used in other systems, although all ASCII characters continue to use the ASCII code points. Character Encoding Form (CEF): This component explains how to map code points to code units. Character Encoding Scheme (CES...
In this step you will normalize Unicode strings with thenormalize()function from Python’s unicodedata library in theunicodedatamodule, which provides character lookup and normalization capabilities. Thenormalize()function can take a normalization form as its first argument and the string being normalized...

In Python, code points are written in the form \uXXXX, where XXXX is the number in four-digit hexadecimal form(十六进制). Within a program, we can manipulate Unicode strings just like normal strings. However, when Unicode characters are stored in files or displayed on a terminal, they ...

Theiri_to_uri()function will not change ASCII characters that are otherwise permitted in a URL. So, for example, the character ‘%’ is not further encoded when passed toiri_to_uri(). This means you can pass a full URL to this function and it will not mess up the query string or ...
Humans use text. Computers speak bytes. Esther Nam and Travis Fischer, “Character Encoding and Unicode in Python”1Python 3 introduced a sharp distinction between strings of human text and sequences of raw bytes. Implicit conversion of byte sequences to Unicode text is a thing of the past. ...
