emoji character

when you have an emoji character, the character size is 2, so you should move 2 characters instead of one. Otherwise the cursor will move to an invisible position..

Good point. I'll look into it.

you can use this to get the character length:

NSRange nextRange = [textView.text rangeOfComposedCharacterSequenceAtIndex:textView.selectedRange.location];
