Encoding used in resource files is not UTF-8

Encoding used in resource files is not UTF-8

XML supports encoding in a wide variety of character sets. However, not all tools handle the XML encoding attribute correctly, and nearly all Android apps use UTF-8, so by using UTF-8 you can protect yourself against subtle bugs when using non-ASCII characters.

In particular, the Android Gradle build system will merge resource XML files assuming the resource files are using UTF-8 encoding.
