<p>总是有正则表达式;只需在方括号内列出所有有问题的字符,如下所示:</p>
<pre><code>import re
print re.sub(r'[\xc2\x99]'," ","Hello\xc2There\x99")
</code></pre>
<p>这将打印“Hello There”,不需要的字符将替换为空格。</p>
<p>或者,如果每个字符有不同的替换字符:</p>
<pre><code># remove annoying characters
chars = {
'\xc2\x82' : ',', # High code comma
'\xc2\x84' : ',,', # High code double comma
'\xc2\x85' : '...', # Tripple dot
'\xc2\x88' : '^', # High carat
'\xc2\x91' : '\x27', # Forward single quote
'\xc2\x92' : '\x27', # Reverse single quote
'\xc2\x93' : '\x22', # Forward double quote
'\xc2\x94' : '\x22', # Reverse double quote
'\xc2\x95' : ' ',
'\xc2\x96' : '-', # High hyphen
'\xc2\x97' : '--', # Double hyphen
'\xc2\x99' : ' ',
'\xc2\xa0' : ' ',
'\xc2\xa6' : '|', # Split vertical bar
'\xc2\xab' : '<<', # Double less than
'\xc2\xbb' : '>>', # Double greater than
'\xc2\xbc' : '1/4', # one quarter
'\xc2\xbd' : '1/2', # one half
'\xc2\xbe' : '3/4', # three quarters
'\xca\xbf' : '\x27', # c-single quote
'\xcc\xa8' : '', # modifier - under curve
'\xcc\xb1' : '' # modifier - under line

return re.sub('(' + '|'.join(chars.keys()) + ')', replace_chars, text)
