Build Fails to Copy Resources with Special Characters in File Name

When files in the resources folder have file names containing supplementary characters / surrogate pairs, Gradle is not capable of copying them to the build folder and fails hard.

Gradle Version: 3.1
Operating System: MAC OS X El Capitan
JVM Version:
java version "1.8.0_51"
Java™ SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot™ 64-Bit Server VM (build 25.51-b03, mixed mode)

Is this a regression? If yes, which version of Gradle do you know it last worked for?
No, tested on 2.N series and also failing

Link to Example Project. Works with Maven, fails with Gradle:

Hi Conor,

Thanks a lot for the report and the reproducer project!
I filled a GitHub issue to track it.
