当文本分析遇到乱码(ง'⌣')ง怎么办？
做文本分析经常遇到数据乱码问题，一般遇到编码问题我们无能为力，都是忽略乱码的文本。
text = open(file, errors='ignore').read()但是这样会遗失掉一些信息，那到底怎么治文本分析时经常为非作歹的妖魔鬼怪？
心里默念python大法好！ftfy（fixes text for you）可以为我们整理的乱码数据。
安装
!pip3 install ftfy==5.6乱码(ง'⌣')ง例子
只我在官方文档上找到这些奇形怪状的字符串，相信大家可能有的也见过这些数据。

Broken text… it’s flubberific!

This string is made of two things:\u2029 1. Unicode\u2028 2. Spiteftfy.fix_text：专治各种不符
使用ftfy中的fix_text函数可以制伏绝大多数(ง'⌣')à
from ftfy import fix_text
fix_text("(ง'⌣')ง")"(ง'⌣')ง"fix_text('ünicode')'ünicode'fix_text('Broken text… it’s flubberific!')"Broken text… it's flubberific!"fix_text('HTML entities <3')'HTML entities <3'fix_text("¯\\_(ã\x83\x84)_/¯")'¯\\_(ツ)_/¯'fix_text('\ufeffParty like\nit’s 1999!')"Party like\nit's 1999!"fix_text('ＬＯＵＤ ＮＯＩＳＥＳ')'LOUD NOISES'fix_text('único')'único'fix_text('This — should be an em dash')'This — should be an em dash'fix_text('This text is sad .â\x81”.')'This text is sad .⁔.'fix_text('The more you know 🌠')'The more you know ?'fix_text('This text was never UTF-8 at all\x85')'This text was never UTF-8 at all…'fix_text("\033[36;44mI'm blue, da ba dee da ba doo...\033[0m")"I'm blue, da ba dee da ba doo..."fix_text('\u201chere\u2019s a test\u201d')'"here\'s a test"'text = "This string is made of two things:\u2029 1. Unicode\u2028 2. Spite"
fix_text(text)dd'This string is made of two things:\n 1. Unicode\n 2. Spite'
ftfy.fix_file：专治各种不符的文件
上面的例子都是制伏字符串，实际上ftfy还可以直接处理乱码的文件。这里我就不做演示了，大家以后遇到乱码就知道有个叫fixes text for you的ftfy库可以帮助我们fix_text 和 fix_file。
