unity menu reads international characters improperly: e.g. men'u instead of menú

Binary package hint: unity

The menu that appears when you press the Windows key or Alt-F2 does not read tildes properly.
If you type 'adiós', it reads 'adi'os'.
I tried this with the Spain keyboard layout.

This is the type of bugs english speakers tend to miss.
