Phpstorm Setting the Encoding

Yesterday with Phpstorm Open ASP program (need in Phpstorm plug-in to open the ASP support, only highlight), found all the Chinese is garbled.
It is clear that ASP, mostly GBK encoded, and phpstorm default is Utf-8.
Very convenient, in the settings to adjust the fileencoding to GBK OK. But then, still can not see the effect, and then open any file, or garbled
Do not be nervous, will phpstorm quit a bit again in OK.
