1. Create any QML with a string property, like a Text{}
2. Insert with any escaped UTF character in the string on the code view, say "\uf078"
3. Copy and paste it on the Designer.
4. It's UTF character will be unescaped and replaced with a possibly non printable character, making the code less readable.

Expected behavior: To copy and paste "as is", if it's encoded then encoded; if explicit then explicit.
