Invalid character in identifier

I have some code that includes:

def analysis_result (results):
 keys = analysis.keys ()
 values ​​= list(analysis.values ​​())
 values.sort (reverse = True )
 # More code...

But I get an error from the values ​​= list(analysis.values ​​()) line that says SyntaxError: invalid character in identifier. Why? What is wrong with the code, and how do I fix it?

Note carefully that retyping the code as it appears does not cause a SyntaxError, but copying and pasting it does.

The error here is due to non-printing text that cannot be seen in the code example. Do not close the question as not reproducible, and take special care when editing. At some prior point in the question's history, it was edited to try to "show" the invalid character by using a backslash escape sequence. This does not work; we can only see this by treating the code as a string and asking Python for a string representation. While it would also be incorrect to type code that uses backslash escape sequences, the error message would be different.

    Welcome to Stack Overflow. Before answering an old question having (many) other answers already ensure your answer adds something new or is otherwise helpful in relation to them. As such the answer from Yigit Alparslan points out a similar problem/solution for the minus - sign; however providing more context. – For this question an arbitrary number of answers could be posted by looking at each character individually having a subtle encoding issue. But what's the value of that? Commented Sep 19, 2020 at 1:19
