my application crashes

 File "c:\users\tausif\appdata\local\programs\python\python38-32\lib\csv.py", line 154, in writerow
    return self.writer.writerow(self._dict_to_list(rowdict))
  File "c:\users\tausif\appdata\local\programs\python\python38-32\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 22-29: character maps to <undefined>

I know this error is occurring due to a Hindi Language character.

The default encoding for files in Windows is the process active code page, which defaults to the system code page, e.g. code page 1252 if the system locale is "en-IN". You need to explicitly use a Unicode encoding such as UTF-8 when opening the file, e.g. open('some.csv', newline='', encoding='utf-8').

You can learn more about unicode and encodings:
