Auto completion of accents and tilde OSX I've been working on macs for a couple of years now, and recently switched jobs (Software dev).
Before when I  was typing something like "e would not automatically merge into ë. This is really annoying in terminal And I don't know how to disable this as of now (I googled but not sure what I should be looking for). One of the most annoying things I encountered was when I need to go to my home dir in terminal (using tilde) when tying by default it will complete to ˜/ whilst I would like to see it act like before: ~/ which requires me to type an extra space.

I never need the auto completion for accents since I'll use the menu which opens when you hold the key instead.

Does anyone know what could cause and get rid of this behaviour.

My keyboard settings are US-Internation (which is normal in the Netherlands) and my MacBook is fully updated to El-Capitan.
I had same problem, just change U.S. International - PC input source for U.S.
