Problem in inserting special character in non-keypad keyboard

Problem in inserting special characters in non-keypad keyboard
I have got a problem inserting special characters in my word document like “è” in Resume.
To do the job before, I use the ALT + [decimal value of the character] on the keypad.
This trick does not work using the numbers on the keyboard.
For example, then is equivalent to ALT + 164.
