That would happen if the string is part of an (event) attribute. In that 
case, if you need to include both the Ascii apostrophe (') and the Ascii 
quotation mark in the same attribute value, then you need to use HTML 
escape for either of them, e.g.

title='Please don't click the "Click" button again'

If the string needs to appear between quotation marks in JavaScript 
code, like alert('...'), then things get even more inconvenient.

But you normally avoid these issues by placing JavaScript code in 
<script> elements, or better still in external files. Even if the event 
handler is simple, it may pay off to write it as a function, say

function alarm() {
   alert('Please don\'t click the "Click" button again');
}

and then the event attribute is simple, e.g. onclick="alarm()".
