Word or string position under mouse position

[Whippets]

This is a long shot, but I have a scrollview with a single label in it. The label shows a Rich Text string. Is there any way to capture the position in the string (or the word) that the mouse is over?

Many thanks

//if you are using ngui it is pretty easy actually:

using UnityEngine;
using System.Collections;

public class textTest : MonoBehaviour
{

	// Use this for initialization
	void Start ()
	{

	}

	// Update is called once per frame
	void Update ()
	{

	}

	void OnClick ()
	{

			Vector2 screenPos = Input.mousePosition;
			Camera cam = NGUITools.FindCameraForLayer (gameObject.layer);
			Vector3 worldPos = cam.ScreenToWorldPoint (screenPos);
			
			int testCharIndex = GetComponent<UILabel> ().GetCharacterIndexAtPosition (worldPos);
			string theWord = GetComponent<UILabel> ().GetWordAtPosition (worldPos);
			print (testCharIndex);
			print (theWord);
		
	}

}
