Creating JSON shows error Invalid characters found
<p>Hi am trying to create a JSON Object but it shows error invalid characters found this is my JSON.</p>

<pre><code>{
    "title":"Biology",
    "content":"Egg period: 4 -6 days \n
           Eggs laid in cracks and crevices of the loose bark on the trunk \n
            Eggs: ovoid or elliptical and dirty white in colour \n
            Adult :Reddish brown in colour",
    "isSubtitle":"N"
  } 
</code></pre>

<p>Please help to fix this and explain the cases of invalid characters in making JSON will be helpful.</p>
