title: TypeScript generated JS files encoding
body: <p>I am using VS2015 and latest TypeScript (1.6.3). The generated JavaScript and map files are generated in Windows-1252 encoding. The source TypeScript  files are UTF-8 with BOM.
  I do need the generated files to be UTF-8 with BOM as well in order to pass Windows Store certification. </p>
  
  <p>Once I manually fix encoding of the generated files it's fine. But then I must include the generated files in source control and fix any newly added files.</p>
  
  <p>There doesn't seem to be any settings to change the encoding.
  Is this a bug in the compiler?</p>
  
  <p>The project type is <code>jsproj</code>, which doesn't seem to support <code>tsconfig.json</code> according to <a href="https://github.com/Microsoft/TypeScript/issues/3124" rel="nofollow">https://github.com/Microsoft/TypeScript/issues/3124</a></p>
