从python中的内置未知字符替换字符串

Question

I'm trying to replace this unrecognized text below here to a another text. What I did is decode it to UTF-8 and try to replace the unknown text below.

" you "

varlistlabela = spss.GetVariableLabel(var)
varlistlabela=varlistlabela.decode("cp1252").replace(r'[\u0020-\ud7ff]',"").encode("cp1252") 

Answer 1

You need a regex substitution:

re.sub(r'[^\u0020-\ud7ff]', '', s)

where s is the input string.

Code :

import re

s = " you�"
print(re.sub(r'[^\u0020-\ud7ff]', '', s))
#  you
