Error on 'velocity = [Vector3].normalized'?

Hai guys! I'm getting a weird error I have never seen before:

 Assets/SpaceShooter/Scripts/AI_BehaviorScripts/BombScript.js(27,92): BCE0044: unexpected char: 0xAD.

On the line:

 velocity = moveDirection.normalized * speed­;

Here's the whole script:

 var speed = 5;
 var rotateSpeed = 50;
 
 var maxScanning = 40;
 var blastRadius = 10;
 
 var explosionPrefab : Transform;
 
 private var follow = false;
 private var target : Transform;
 
 function Update () 
 {
         if(follow)
         {
                 var t : Vector3 = target.transform.position;
                 var moveDirection : Vector3 = t - transform.position;
                     
                 var velocity = rigidbody.velocity;
                     
                 if(moveDirection.magnitude<1)
                 {    
                         velocity = Vector3.zero;
                 }    
                 else
                 {    
                         velocity = moveDirection.normalized * speed­;
                 }    
                 
                 rigidbody.velocity = velocity;
         }
         else
         {
                 transform.Rotate(0,rotateSpeed*Time.deltaTime,0);
         }
         
         var hit : RaycastHit;
         
         var direction = transform.TransformDirection (Vector3.forward);
         
         if (Physics.Raycast (transform.position, direction, hit, maxScanning))
         {
                 if(hit.collider.tag == "Player")
                 {
                         follow = true;
                         target = hit.collider.transform;
                         if(hit.distance < blastRadius)
                         {
                                 //blow up and hurt the player
                                 Destroy(gameObject);
                                 var exp = Instantiate(explosionPrefab, transform.position, Quaternion.identity);
                                 //this enemy is only in multiplayer
                         }
                 }
                 else
                 {
                         follow = false;
                 }
            }
 }

Anyone know what's going on with it?!
