Most web designers and developers do not need any instructions for dealing with character encoding.

You should be able to breeze through these topics if you have at least a beginner’s understanding towards digital documents. Basic HTML isn’t required although these techniques mostly apply to web files such as HTML, CSS, and PHP.
