into a double-byte, only need to fill the high byte all 0 can be.Because Python was born earlier than the Unicode standard, the earliest Python only supported ASCII encoding, and the normal string ' ABC ' was ASCII-encoded inside python. Python later added support for

2007-12-13 10:50:47| Category: Python utility software compilation | Report | Font size Subscription ASCII is a character set, including uppercase and lowercase letters, numbers, control characters, etc., which are represented by a byte, with a range of 0-127Unicode is divided into UTF-8 and UTF-16. UTF-8 variable length, up to 6 bytes, characters less than 127 are expressed in one byte, and as with the ASCII character set, the English text unde

-8 code exampleTaking the Chinese character "Yan" as an example, demonstrates how to implement UTF-8 coding.Known as "Strict" Unicode is 4E25 (100111000100101), according to the table above, you can find 4E25 in the range of the third row (0000 0800-0000 FFFF), so "strict" UTF-8 encoding requires three bytes, that is, the format is " 1110xxxx 10xxxxxx 10xxxxxx ". Then, starting from the last bits of "Yan",

15.14 Pass a Unicode string to the C function library?To write an extension, you need to pass a Python string to a library function in C, but this function does not know what to do with Unicode.Solution?There are a number of issues to consider here, but the main problem is that the existing C library does not understand the native Unicode representation of Python

First, what is UnicodeBefore Unicode, people used ASCII code, that is, each English character is stored in a 7-bit binary number in the computer, the range is 32-126, so the ASCII character can only represent 95 printable characters, although the number of bits is then extended to 8 bits, But it can still represent up to 233 characters, which is a huge limitation for thousands of non-European languages.Unicode breaks the ASCII limit by using one or mo

Answer: (http://stackoverflow.com/) PS: This website solves my many questions ah, everybody more on>>>s= ' \u9648\u4f1f\u9706\u5176\u5b9e\u662f\u4e2a ' >>>print s.decode (' Unicode-escape ') >> > This is actually a　　First you have a string similar to this:\u9648\u4f1f\u9706\u5176\u5b9e\u662f\u4e2aSo you try to print directly, hoping to become Chinese>>>s = ' \u9648\u4f1f\u9706\u5176\u5b9e\u662f\u4e2a ' >>>print s>>>\u9648\u4f1f\u9706\ U5176\u5b9e\u662

ObjectiveSometimes the return value from the interface is encoded in a format similar to "%u4e0a%u6d77%u60a0%u60a0", not the Unicode encoding in Python.The Unicode encoding inside Python should be this format: \u4e0a\u6d77\u60a0\u60a0Unicode encoding-python21. First look at the Unicode encoding for

ASCII is a character set, including uppercase and lowercase English letters, numbers, and control characters. It is represented in one byte and ranges from 0 to 127. Unicode is divided into UTF-8 and UTF-16. UTF-8 variable length, up to 6 bytes, less than 127 characters are represented in one byte, the same as the results of the ASCII character set, english text under ASCII encoding can be treated as UTF-8 encoding without modification.

Take a look at Liaoche's Python2.7 tutorial in the afternoon, see the string and Encode section, have a little feeling, combine Cia Qingcai's Python blog to record this feeling:ASCII: is a byte (8bit, 0-255) of 127 letters for uppercase and lowercase letters, numbers and some symbols. It is mainly used to denote modern English and Western European languages.So there is a problem in dealing with Chinese, because Chinese processing requires at least two

computer. Unicode is created to address the limitations of traditional character encoding schemes, which set a uniform and unique binary encoding for each character in each language to meet the requirements of cross-language, cross-platform text conversion and processing. Unicode specifies that all characters and symbols are represented with a minimum of 2 bytes (16 bits), i.e. 2**16-1=65535UTF-8, which is

ASCII is a character set, including uppercase and lowercase letters, numbers, control characters, etc., which are represented by a byte, and the range is 0-127 Unicode into UTF-8 and UTF-16. UTF-8 variable length, up to 6 bytes, less than 127 characters in a byte, as in the case of the ASCII character set, the English text under ASCII encoding does not need to be modified to be treated as a UTF-8 encoding.
