On 4.1 it crashed Unity
But on 4.2 and 4.3 - Unity gives error that it can't import this package

1 Download attached test.zip
2 Unzip it
3 Create new project and try to import package from "test\哦獭遤额\阿呵答"
4 Unity should give an error in console:

Failed importing package D:/test/哦獭遤额/阿呵答/case_544754-May29th_WithEnemyAttack_.unitypackage
UnityEditorInternal.InternalEditorUtility:ProjectWindowDrag(HierarchyProperty, Boolean)
UnityEditor.DockArea:OnGUI()

(May be you should set "the language for non
Unicode programs" to Chinese Simplified PRC to reproduce it - as described in pictures attached in history of this report)
