This looks like an encoding issue. In Android Studio the encoding is set to UTF-8, but I don't see it specified in Notepad. In Notepad, use the Save As dialog and set the Encoding dropdown to UTF-8. It should then load properly in Android Studio.

Read Mismatched Encoding

The encoding used to compile your project is specified in the build.gradle files. The default, which is used when no specific encoding is specified, is UTF-8. We strongly recommend you use UTF-8 encoding whenever possible.

File -> Settings-> Search -> File Encoding->Global Encoding->UTF-8
