Regex for breaking repeated characters
<p>I have a comment box on my site , what I want here is if a user writes input (any character) which is more than 20 characters and doesnot put space between them then it should place a space between it. </p>

<p>Like: "asdasdasdasdasdasdasdasd"</p>

<p>Parsed: "asdasdasdasdasdasdas dasd"</p>

<p>I think it can be done with string compare but I want the regex to match it or the full solution. Thanks for any help.</p>
