Current Behavior

If a file has a non-BMP character in its name, storing the build cache will fail:

> Failed to store cache entry 9ea8bf46385e31b90193de4ce7d435c6 for task ':compileJava': Could not pack tree 'destinationDirectory': Could not get file mode for '<project dir>/build/classes/java/main/Main𓊖.class'.

Expected Behavior

The build cache should function normally.

Context (optional)

Since we now emit Unicode from test names due to the reporting refactoring, it's much easier for non-BMP characters to end up in the output.

Self-contained Reproducer Project

Put the following in Main𓊖.java: public class Main𓊖 {}

Then run gradle compileJava --build-cache --rerun.
