Answer 1

Solution for windows 10:

Open command prompt(CMD)

1. open command prompt.
2. type chcp and hit Enter.
3. if output for chcp command is : Active code page: 65001 then: go to the control panel -> Region -> "Administrative" tab -> Change system locale -> Uncheck "Beta: Use Unicode UTF-8 for worldwide support".
4. Restart your PC.
5. Again check system local for 'beta' if it is unchecked then all is ok.
6. if it is checked again then try to change your native language to English.
