eclipse automatic file encoding detection -

Is there a way to auto-detect the fault file type?

I have tried to do

  eclipse-preferences-> general-> content-type-> default- encoding  

And to put file-type, for example UTF-8, but then it shows all the files in the project with encoding, while some other files have a different encoding, so some letters encode these files badly Are there.

Then I know that I have a file encoding

  file-> Priorities- & gt; Right-click on resources  

But instead of assuming it, I would like one way to get it echoed out for all those bad encoded files one by one.

They are mostly php files.
