CG Shader Properties Parse Error

This is the strangest thing I have ever seen in all my programming experience. Here's the situation -

 Shader "SomeShader" {
     Properties {
         _MainTex ("Base (RGB)", 2D) = "white" {}
         _Color("Diffuse Color", Color) = (1.0, 1.0, 1.0, 1.0)
         _SquashAmount (“Squash”, Float) = 1
         //_SquashAmount ("Squash", Float) = 1
     }

The code above does not work. But this -

 Shader "SomeShader" {
     Properties {
         _MainTex ("Base (RGB)", 2D) = "white" {}
         _Color("Diffuse Color", Color) = (1.0, 1.0, 1.0, 1.0)
         //_SquashAmount (“Squash”, Float) = 1
         _SquashAmount ("Squash", Float) = 1
     }

This code above works.

Basically getting a parse error. I have tried many times and the second SquashAmount line always works while the first does not. I swear I'm not lying.

Can anyone demystify this?

Thanks.
