Python源代码默认是 ASCII.可以在源文件的第一行或者是第二行作如下声明: # coding=UTF-8 or (using formats recognized by popular editors): 1 2 #!/usr/bin/python# -*- coding: UTF-8 -*- or: 1 2 #!/usr/bin/python# vim: set fileencoding=UTF
Warning: (3719, "'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release. Please consider using UTF8MB4 in order to be unambiguous.") 怎么解决?最简单办法是:将原来的CHARSET=utf8修改为CHARSET=utf8mb4即可! createtablexiangjiaosp...
参考上述getBytes的例子,"gbk" 和"utf8"都可以得出正确的结果"4e2d 6587",但iso8859-1最后变成了"003f 003f"(两个问号)。 因为utf8可以用来表示/编码所有字符,所以new String( str.getBytes( "utf8" ), "utf8" ) === str,即完全可逆。 3.3. setCharacterEncoding() 该函数用来设置http请求或者相应的...

Python parser to interpret the file using the given encoding. Most notably this enhances the interpretation of Unicode literals in the source code and makes it possible to write Unicode literals using e.g. UTF-8 directly in an Unicode aware editor. ...
[字符编码ASCII,Unicode和UTF-8] 主要非英文字符集的编码范围 匹配所有中日韩非符号字符,那么正则表达式应该是^[\u2E80-\u9FFF]+Undefined control sequence \u, 需要注意的是^[\u4E00-\u9FA5]+Undefined control sequence \u也是一样的结果。 皮皮Blog ...
