A filesystem example

This file has special characters in it:
!@#$%^&*()_+|~{}:"<>?/.,;'[]\=-`
If you look at the HTML code for this when it is in the
browser, you will notice that the following characters:
	<>&
have been replaced with special HTML tags.
If you want to display text in a webpage that contains
these characters, you have to convert to these tags.
Otherwise your page will display very strangley.
