* Tweak your LANG environment variable to include an encoding: e.g. change en_AU to en_AU.UTF-8
* Run Gradle with GRADLE_OPTS=-Dorg.gradle.native=false to disable the new native stuff (but don't forget to remove it after you upgrade to Gradle 1.4). The switch has to be in GRADLE_OPTS, it won't work if you run gradle -Dorg.gradle.native=false or add it to your gradle.properties.
* Wait for a Gradle snapshot with a fix in the near future.
