JavaFX Aritifacts Title can NOT set Chinese

Hi, 

On a Java FX project, follow these steps:

Project Structure -> Artifacts -> Java FX, if input Chinese in the Title field, then the build will fail:

Error:Java FX Packager: 
BUILD FAILED
Error reading project file C:\Users\XXXXX\.IdeaIC2018.2\system\compile-server\hiright_17de5f6b\_temp_\build.xml: 2 字节的 UTF-8 序列的字节 2 无效。
Total time: 0 seconds

Is this a bug, or I need do something else?
