Unmappable character for encoding UTF-8 in Android Studio

After importing project from eclipse into Android Studio i have got the following error :

Error: unmappable character for encoding UTF-8

To fix this issue, Open the File with the encoding issue. Go to File menu-> Select File

 

You’ll see a Drop down list of different Encodings, Select more ->


 

then Select UTF-8.

and then you will see a dialog with Reload and Convert buttons, Select Convert option.

 

and build the project.

On left Panel  Goto Project Settings select File Encodings change the Project Encoding to UTF-8
