My wife has a Greek keyboard on her iStuff. I just tried it. It's a tap on the little globe to the left of the spacebar - or a long-tap and a second tap to select Greek - to change the keyboard and another tab or two to return to English. So add a Turkish keyboard. I don't know how you do that but I can guess.

Same on Android which I use.
