Tutorial 17: Shady Characters
Summary
In this tutorial, you learned the difference between a character
set and a character encoding. You learned how to select a character
encoding for your documents and how to specify it so that user agents
can use it. You also learned how to use character references to insert
characters into your document in order to use characters outside the
scope of your selected encoding or to make sure they are not
considered markup. In the next tutorial, we will examine how you can
specify the language of your document to aid readers and user agents
in understanding your documents.
