python string unicode issue

Question

Here is my code (I am using python 2.7 )

    result = " '{0}' is unicode or something: ".format(mongdb['field'])
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb0' in position 27: ordinal not in range(128)

It looks like a string I read from mongodb contains unicode. And it throws this error. How to fix it to concatenate this unicde with custom string 'is unicode or something:' ?

Thanks in advance

UPDATE

result = u" '{0}' is unicode or something: ".format(mongdb['field']) 

works for me

Answer 1

Use a unicode format string (recommended):

result = u" '{0}' is unicode or something: ".format(mongdb['field'])

Or encode the field:

result = " '{0}' is unicode or something: ".format(mongdb['field'].encode('utf-8'))
