This is a "Dead Keys" issue. You are probably using a different layout from the standard US layout.
Pressing ' and then e, for example, will produce an é and pressing ~ and a will produce an ã.
Check your keyboard and regional settings.
I'n now at work (on a Winblows workstation) and thus am unable to guide you directly to the setting, but when I'll get home I'll let you know.
Also note that pressing ' or ~ and then the spacebar, will produce the desired character directly.
