Using 14.04 with keyboard selected as 'US international with dead keys' as my keyboard layout option, (so that I may use characters from other languages) and the system accepts text input as you would expect.
Chrome however fails to recognise what keyboard I have set in system settings, no dead key input is detected or used by Chrome at all, frustratingly.
I updated from M34 to Version 36.0.1985.125 to no avail :(
