python如何将ascii代码转换为原始字符

Question

Using python 2.7.2

I'm having issues with special characters with ascii values > 128

The problem is that our data got corrupted by iso vs utf8 convertion. so We are trying to fix this.

Where are trying to fix it using python. We loop through our data character by character fix the corrupted values. and get an ascii # code. let say I want to replace ascii code 226 with ascii code 146, which is a special quote "'":

c='â'
   print ord ( c ) 
   226 

How can I decode 226 back to â or convert ascii 146 to "'"?

Answer 1

Instead of the chr function you will want the unichr function:

 >>> c = u'â'
 >>> print(ord(c))
 226
 >>> unichr(226)
 u'\xe2'
 >>> print(unichr(226))
 â

See https://docs.python.org/2/howto/unicode.html

Answer 2

You probably want the chr function. Or is your problem that you don't have the right codepage?
