How to fix broken utf-8 encoding in Python?

问题:

My string is Niệm Bồ Tát (Thiá»n sÆ° Nhất Hạnh) and I want to decode it to Niệm Bồ Tát (Thiền sư Nhất Hạnh). I see in that site can do that http://www.enderminh.com/minh/utf8-to-unicode-converter.aspx

and I start to try by Python

mystr = '09. Bát Nhã Tâm Kinh'
mystr.decode('utf-8')

but actually it is not correct because original string is utf-8 but the string show is not my expecting result.

Note: it is Vietnamese character.

How to resolve that case? Is that Windows Unicode or something? How to detect the encoding here.

I'm not sure what you can do with these kind of data, but for your example in your original post, this works:

>>> mystr = '09. Bát Nhã Tâm Kinh'
>>> s = mystr.decode('utf8').encode('latin1').decode('utf8')
>>> s
u'09. B\xe1t Nh\xe3 T\xe2m Kinh'
>>> print(s)
09. Bát Nhã Tâm Kinh

The only thing that helped me with broken cyrillic string - https://github.com/LuminosoInsight/python-ftfy

This module fixes pretty much everything and works much better than online decoders.

>>> from ftfy import fix_encoding
>>> mystr = '09. Bát Nhã Tâm Kinh'
>>> fix_encoding(mystr)
'09. Bát Nhã Tâm Kinh'

It can be easily installed using pip install ftfy
