Unity Dash Search Box doesn't works correctly in keyboard layouts with dead keys

[Tiago Hillebrandt]

Binary package hint: unity

My keyboard layout is defined as USA International (with dead keys) and is working correctly in any applications except on Unity Dash Search Box.

When I press the dead key I can see itself instead generate a not visible dead key until I press next key, like you can in attached image.
