For some reasons my file encoded by GBK.
When I import the module to IDEA, I must set every file in status bar from UTF8 to GBK.
But I already read the online web documents, set the IDE encoding and project encoding to GBK.(I do the set encoding action after import the project)
And, it not always be able to set the file's encoding, the status bar is gray.
The document says the encoding is not configured, but why?
