1.在python2默认编码是ASCII, python3里默认是utf-8 2.unicode 分为 utf-32(占4个字节),utf-16(占两个字节),utf-8(占1-4个字节), so utf-16就是现在最常用的unicode版本, 不过在文件里存的还是utf-8,因为utf8省空间 3.在py3中encode,在转码的同时还会把string 变成bytes类型,decode在解码的同时还会...
2. Remove the warning, and change the default encoding to "ascii". The builtin compile() API will be enhanced to accept Unicode as input. 8-bit string input is subject to the standard procedure for encoding detection as described above. If a Unicode string with a coding declaration is pas...

Encoding UTF-8 Python 环境 首先使用python -V检查你的Python版本,如果你的版本是2.7或以上,那么就不需要做任何操作,可以直接安装bypy,但是如果你像我一样多数是CentOS 6.x 那么就需要先升级Python版本。我这里是将Python升级到2.7。 Install Python 2.7 ...
