Nope, the file itself still has the two characters separately—it just shows up as a combined character, taking up twice the space. So pressing Backspace on ≠ gives you !.
It doesn't really take any getting used to, since the characters are all still there, just displayed slightly differently. If anything it's made my code more intuitive because I can see where one operator ends and another begins 
That's exactly what i mean: Stuff gets displayed differently. So it would take at first longer for me to realise what a certain piece of code means, as i'm soooooo used to != and === and stuff like that...
