How to make “Datastore Viewer” of “Development Console” of “Google App Engine” show Unicode?

[Hung Ha]

Look at the following picture of "Datastore Viewer" of "Development Console" of "Google App Engine". Look at "First Name", it showed "th?y" instead of "thủy" (the correct format one).

Now, look at the real Datastore of Google AppEngine below. It showed "thủy" correctly

SO, How to make "Datastore Viewer" of "Development Console" of "Google App Engine" show Unicode?

The first (not working) picture is from the old, deprecated App Engine console. The second (working) picture is from the new Developers Console, which is what you should be using.
