Using the Python ord() function gives you the base-10 code point for a single str character. The right hand side of the colon is the format specifier. 08 means width 8, 0 padded, and the b functions as a sign to output the resulting number in base 2 (binary). This trick is ...

字符无法处理 后来某些二进制数固定下来代表某个字符 形成了字符集 从博多码(5bits)到 BCDIC(6bits) 再到EBCDIC码(8bits) 最后统一于ascii 但是 各国家和地区 都有 自己的文字 这一领域 没有 统一的标准 所以每个国家和地区 都制定自己的编码标准
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...
Chapter 4. Unicode Text Versus Bytes Humans use text. Computers speak bytes. Esther Nam and Travis Fischer, “Character Encoding and Unicode in Python”1 Python 3 introduced a sharp distinction … - Selection from Fluent Python, 2nd Edition [Book]
Unicode provides many different character properties. The most often needed ones are available through these macros which are mapped to C functions depending on the Python configuration. int Py_UNICODE_ISSPACE(Py_UCS4 ch) Return 1 or 0 depending on whether ch is a whitespace character. int Py_...
1.char16_t与char32_t 在C++98中,为了支持Unicode字符,使用wchar_t类型来表示“宽字符”,但并没有严格规定位宽,而是让wchar_t的宽度由编译器实现,因此不同的编译器有着不同的实现方式...4.Unicode的库支持 C++11在标准库中增加了一些Unicode编码转换的函数,开发人...
