Why is this object property undefined?

Question

Consider the code below. The first console.log correctly logs the image, and you can see its properties in the image below. However, when I try logging one if its p

I think the object keys have unprintable characters, such can be replicated like this:

var obj = {};
obj["E"+String.fromCharCode(15)] = new Array(15);

console.log(obj);

/*Object
E: Array[15]
__proto__: Object*/

console.log(obj.E)

//undefined

console.log( obj["E"+String.fromCharCode(15)] )

//[]

Edit: you can see if this is the case for your object keys:

var realKeys = [];

for( var key in obj ) {
realKeys.push( [].slice.call( key ).map( function(v){return v.charCodeAt(0);} ).join(" ") );
}

//["69 15"] (69 stands for the letter "E" and 15 was the unprintable character I added manually)

Edit2: Since you can't do that I came up with another way to see if there are unprintable characters:

Copypaste the key string like this: (go all the way as much as you can on both ends so you pick any invisible characters)

Then dump your clipboard like this (Make sure you are using double quotes):
