UnicodeEncodeError: 'charmap' codec can't encode characters

I was getting the same UnicodeEncodeError when saving scraped web content to a file. To fix it I replaced this code:

with open(fname, "w") as f:
    f.write(html)

with this:

with open(fname, "w", encoding="utf-8") as f:
    f.write(html)

If you need to support Python 2, then use this:

import io
with io.open(fname, "w", encoding="utf-8") as f:
    f.write(html)

If you want to use a different encoding than UTF-8, specify whatever your actual encoding is for encoding.

I fixed it by adding .encode("utf-8") to soup.

That means that print(soup) becomes print(soup.encode("utf-8")).

In Python 3.7, and running Windows 10 this worked (I am not sure whether it will work on other platforms and/or other versions of Python) Replacing this line:

with open('filename', 'w') as f:

With this:

with open('filename', 'w', encoding='utf-8') as f:

The reason why it is working is because the encoding is changed to UTF-8 when using the file, so characters in UTF-8 are able to be converted to text, instead of returning an error when it encounters a UTF-8 character that is not suppord by the current encoding.

While saving the response of get request, same error was thrown on Python 3.7 on window 10. The response received from the URL, encoding was UTF-8 so it is always recommended to check the encoding so same can be passed to avoid such trivial issue as it really kills lots of time in production

import requests
resp = requests.get('https://en.wikipedia.org/wiki/NIFTY_50')
print(resp.encoding)
with open ('NiftyList.txt', 'w') as f:
    f.write(resp.text)

When I added encoding="utf-8" with the open command it saved the file with the correct response

with open ('NiftyList.txt', 'w', encoding="utf-8") as f:
    f.write(resp.text)
