Describe the bug

In the snapshot pasted below, we can see that the app's title bar is showing the correct string with UTF-8 characters. But in the all windows summary, the title shown is incorrect. As per my understanding, these 2 should be same.

How to reproduce

1. Create an app with a tile having utf-8 characters.
2. Open the app. The app will have the title populated as expected.
3. While the app is open, hover the cursor on the "all windows" option as shown in the screenshot above. The title displayed there is not showing the characters correctly.

Pretty sure this is a duplicate of #659 and #3876. Unless anyone can point to a source of data that we are outputting incorrectly it seems to be a bug in the string parsing of Gnome.

If you have more information that shows the error is at our end please do add - but our title bars and desktop file metadata are correctly utf-8 encoded in my testing.
