Note that JDK source code is inconsistent.   The makefile commands for `javac` specify just ASCII (since forever) but the `javadoc` commands allow ISO-8859-1, which was popular before the widespread acceptance of UTF-8.

Ideally, all should be self-consistent -- JDK policy, `javac` commands, `javadoc` commands, DocCheck, etc.
Note that resource files might use different encodings to `*.java` source files.
