If a Text node's content is wrapped, then character index will start from 0 again in the new line or do we expect it to be relative to text node and continue with character index from previous line?
If the latter behavior is expected then I couldn't find a way to differentiate between a text node which is wrapped and which is not. 
Even if warp information is available, the `getOffsetAtX` method returns the offset (character index) based on the x coordinate value which is relative to the new line. If we use run's start value along with the offset, then we get absolute value of character index relative to textflow. So it looks to me that if a Text node's content is wrapped, then character index in the new line will start from 0. In this case insertion index starting from 0 looks to be correct.
