title: Change encoding on a per file or per extension basis
body: <p>I'm using Microsoft Visual Studio Express 2012 for Web.  It seems that every file which I open with it gets encoded into UTF-8.  For most files which are going to be web-facing, that's fine.  However, I have files in my projects that are specifically for build purposes (e.g., <strong>.bat</strong> files), which must be encoded in ANSI.</p>
  
  <p>Are there any configuration settings in VS to either designate on a per file or a per extension basis the encoding? Or, if not specify the encoding, at least disable the auto-conversion to UTF-8?</p>
