Chrome Extension Manifest.json invalid

Question

Now why in the world is this invalid.

Manifest.json:

{
     "name": “mything",
     "version": "1",
     "manifest_version": 2,
     "content_scripts": [{
         "js": [“engine.js”],
         "matches": ["http://www.agar.io/*”]
      }]
}

Error:

Failed to load extension from: ~/Desktop/AgarExpress
Manifest is not valid JSON. Line: 2, column: 15, Unexpected token.

Line that is invalid is

"name": “mything",

Answer 1

If to believe JsonLint “ != " . They dont have the same encoding, i remember i stumbled upon it as an issue with greek keyboard if I am not mistaken. This one is valid, also according to the text coloring of Stack Overflow:

{
    "name": "mything ",
    "version": "1",
    "manifest_version": 2,
    "content_scripts": [{
        "js": ["engine.js"],
        "matches": ["http://www.agar.io/*"]
    }]
}
