One can convert strings between C and Python vice-versa but the C encoding is of a doubtful or unknown nature. Let’s suppose that a given C data is supposed to be UTF-8, but it’s not being strictly enforced. So, it is important to handle such kind of malformed data so that it doesn’t crash Python or destroy the string data in the process.
In the code above, the string sdata contains a mix of malformed data and UTF-8. Nevertheless, if a user calls
print_chars(sdata, slen) in C, it works fine.
Now suppose one wants to convert the contents of sdata into a Python string, further passing that string to the
print_chars() function through an extension. The code given below shows the way that exactly preserves the original data even though there are encoding problems.

Here, one can see that the malformed string got encoded into a Python string without errors and that when passed back into C, it turned back into a byte string that exactly encoded the same bytes as the original C string.
