weird characters in code

I’m brushing up on writing code.
I’m using onChange in a Select and strange characters appear.

[code]
<div>
<select onchange=”location = this.options[this.selectedIndex].value;”>
<option>Please select</option>
<option value=”http://www.apple.com/”>Apple</option>
<option value=”http://www.bbc.com”>BBC</option>
<option value=”http://www.facebook.com”>Facebook</option>
</select>​
</div>
[/code]

this is saved in a html file.

Also in #JavaScript _↴
