Frequently Asked Questions

HTML escaping is the process of converting characters that have special meaning in HTML (<, >, &, ", etc.) into character references so they display correctly in browsers. It also plays an important role in preventing XSS attacks.
The main characters that are escaped are: < becomes &lt;, > becomes &gt;, & becomes &amp;, " becomes &quot;, ' becomes &#x27;. These characters have special meaning in HTML, so they need to be escaped to display as text.
Use HTML escaping when embedding user input into HTML, when displaying HTML tags as text, and as a security measure to prevent XSS attacks. It's essential in web application development.
Use unescaping when you want to convert escaped HTML back to its original form or when restoring escaped data saved in a database. However, use it carefully with understanding of security risks.
