Keep getting unexpected char: 0x200B!

I downloaded a hunger and health script. I saved it as a javascript and I haven't tampered with it or anything yet. I keep getting this error

(26,25): BCE0044: unexpected char: 0x200B.

Can someone please help me with this? Here's the script

 var Health : int = 100;
 var MaxHealth : int = 100;
 var Hunger : int = 100;
 var Timer : float;
 var Texture1 : Texture2D;
 var Texture2 : Texture2D;
 var BarLength : int = 100;
 
 private var Speed : int = 3;
 
 function Update () {
     Health = Mathf.Clamp(Health, 0, MaxHealth);
 
     if(Health > 0){
         Timer += Time.deltaTime;
         
         if(Timer >= Speed) {
             if(Hunger >= 85) {
                 Health += 3;
             }
             if(Hunger <= 0){
                 Health -= 1;
                 Speed = 1;
             }
             else {
             ​       Hunger -= 1;
                 Speed = 3;
             }
             
             Timer = 0;
         }
     }
 }
 
 function OnGUI () {
     GUI.DrawTexture(Rect(400,400,100*Hunger/BarLength,20),Texture1);
     GUI.DrawTexture(Rect(400,430,100*Health/BarLength,20),Texture2);
 }
