title: EncodingError when cordova-plugin-file
body: <p>I am now developing a cordova app which platform is browser.</p>
  <p>I need to access a text file from local file system, so I am using the cordova-plugin-file.</p>
  <p>But I failed as the exception in my chrome console like this (There is no CLI error):</p>
  <blockquote>
  <p>code: 5</p>
  <p>message: &quot;A URI supplied to the API was malformed, or the resulting Data URL has exceeded the URL length limitations for Data URLs.&quot;</p>
  <p>name: &quot;EncodingError&quot;</p>
  </blockquote>
  <p>as my code blow:</p>
  <pre><code>document.addEventListener('deviceready', dataRead, false);
      function dataRead() {
        window.webkitRequestFileSystem(window.PERSISTENT, 100500*1024*1024, function() {
          window.webkitResolveLocalFileSystemURL(&quot;filesystem:&quot; + cordova.file.applicationDirectory + &quot;1111.csv&quot;, gotFile, fail);
        },function (e) {
          console.log(e);
        });
      }
      function fail(e) {
        console.log(&quot;FileSystem Error&quot;);
        console.dir(e);
      }
  
      function gotFile(fileEntry) {
        fileEntry.file(function(file) {
          var reader = new FileReader();
  
          reader.onloadend = function(e) {
            console.log(&quot;Text is: &quot;+this.result);
          }
  
          reader.readAsText(file);
        });
  
      }
  </code></pre>
  <p>Is my URI illegal or for some other reasons?</p>
  <p>Can anybody point out why? Or show me a right example.</p>
  <p>Any help is appreciated.</p>
