SyntaxError: Non-UTF-8 code starting with '\xe7'

Question

I made a program which contains chinese and russian words, but when I ran it, I had a problem with the encoding

In the code that I shared, a complete sentence with some Russian and Chinese characters is shown. With that variable assignment the SyntaxError arises. But when i write sentence=input(), when the user enters the same sentence no error appears.

SyntaxError: Non-UTF-8 code starting with '\xe5' in file hjs.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

How can I solve it?

Answer 1

First of all, welcome to Stack Overflow! Second, you could solve your problem by using Python 3 or, for Python 2, following what is said in this answer.

But why?

Well, according to the aforementioned PEP 263,

Python will default to ASCII as standard encoding if no other encoding hints are given.

And in the PEP you can see the same thing that the mentioned answer says, to add the line # -*- coding: <encoding name> -*-

And why isn't Python 3 affected by this issue? As said in here,

Since Python 3.0, the language’s str type contains Unicode characters(...)

So there is no need for adding the coding magic comment.

For more on that the full unicode article linked above is a great reading, and as it is a classic in StackOverflow, please see this.
