Behaviour unicode string in python





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I have seen this question I have doubts about how can I convert a var to unicode on running time ?
Is it right use unicode function ?
Are there other way to convert a string on running time ?



print(u'Camiu00f3n') # prints with right special char



name=unicode('Camiu00f3n')

print(name) # prints bad ===> Camiu00f3n



name.encode('latin1')

print(name.decode('latin1')) # prints bad ===> Camiu00f3n



encoded_id = u'abcdxc3x9f'

encoded_id.encode('latin1').decode('utf8')

print encoded_id.encode('latin1').decode('utf8') # prints right


I saw a lot of python unicode questions on stackoverflow but i can't understand this behaviour.

  • uhhhh escape sequences only work in Python unicode literals. If you have data with such escape sequences, you may well have JSON data instead, which uses the same syntax. If so, use a JSON parser for that data.

Its just because of that if you don't specify any encoding for unicode function then :




unicode() will mimic the behaviour of str() except that it returns Unicode strings instead of 8-bit strings. More precisely, if object is a Unicode string or subclass it will return that Unicode string without any additional decoding applied.




So you'll have a str version of your unicode (the Unicode part will be escaped):



>>> name=unicode('Camiu00f3n')

>>> print(name)

Camiu00f3n

>>> name

u'Cami\u00f3n'

       ^


For get ride of this problem you can use 'unicode-escape' as your encoding to escape converting the Unicode to string!



>>> name=unicode('Camiu00f3n','unicode-escape')

>>> name

u'Camixf3n'

>>> print(name)

    Note that unicode-escape interprets more than just the uhhhh escapes. If there are other `` backslash-escapes in the text, those too will be interpreted, and may not be what you expected.
