Some small coding problems in tutorials/file/filesystem/

[jjinux]

Here are some problems I found while reading: http://www.html5rocks.com/en/tutorials/file/filesystem/

var bb = new BlobBuilder(); // Note: window.WebKitBlobBuilder in Chrome 12.

Uncaught ReferenceError: BlobBuilder is not defined
window.WebKitBlobBuilder is deprecated.
It suggests that you use Blob instead, but that doesn't have the same API.

// Capture current iteration's file in local scope for the getFile() callback.
(function(f) {
  fs.root.getFile(file.name, {create: true, exclusive: true}, function(fileEntry) {
    fileEntry.createWriter(function(fileWriter) {
      fileWriter.write(f); // Note: write() can take a File or Blob object.
    }, errorHandler);
  }, errorHandler);
})(file);

Should it be fs.root.getFile(f.name, ...)?

I'm trying to run the HTML file in the "PUTTING IT ALL TOGETHER" section. When
I copy-and-paste the code into my editor (Sublime Text 2), and then load it in
a browser, I see "​" at the end of the page. I assumed that this was an
encoding issue. The problem went away once I added the following to the head:

<meta http-equiv="content-type" content="text/html; charset=UTF-8" />

Note, I was serving the file using Python's, simple builtin web server which
you can start via:

python -m SimpleHTTPServer

1. I've been waiting to update the BlobBuilder() samples to Blob(). Now that everyone pretty much supports it, let's do it! https://developer.mozilla.org/en-US/docs/DOM/Blob
2. Correct.
3. The meta charset for HTML5 is: <meta charset="utf-8"> The playground demos don't have that, but probably should :\
