Convert text to HTML character codes.
Example use: To allow you to display your email address on your contact page,
while making it a bit more difficult for automated rippers to extract it and spam it.
It will convert the email address: "mailto:firstname.lastname@example.org" to:
Use this instead of plain text in your source HTML and it will help prevent your
email address being picked up by automated page source readers and spammed.
Your page will still be rendered correctly, mailto links still function correctly and
the code will still validate.
Have a look at my contact page, at the source, to see how it can be used.
