Not all text characters available to you for display by a browser can be
typed from the keyboard. And some characters have special meanings,
such as the brackets around tags, which if not somehow differentiated
when used for plain textthe less-than sign ( < ) in a math equation, for
examplewill confuse the browser and trash your document. HTML and
XHTML give you a way to include any of the many different characters
that comprise the Unicode character set anywhere in your text through
a special encoding of its character entity .

XHTML document text formats. We do, however, highly recommend that you adopt a consistent style
so that you and others can easily follow your source documents.
