如何将unicode字符串转换为相应的ascii字符串？

Question

This code:

print u'S\xe9parateur'
str(u'S\xe9parateur')

throws the error:

Séparateur
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 1: ordinal not in range(128)

I used the function str because I want to convert the unicode string u'S\\xe9parateur' to the corresponding ascii string, ie u'S\\xe9parateur' --> 'S\\xc3\\xa9parateur'

Answer 1

That's not a corresponding ASCII string, it's a UTF-8 string. ASCII, definitionally, cannot represent the whole of the Unicode range; UTF-8 can.

To perform the conversion, use the .encode method of unicode objects:

u'S\xe9parateur'.encode('utf-8')

produces 'S\\xc3\\xa9parateur' .
