URIs must be properly escaped, they must not contain unescaped
characters below U+0021 including the space character and not
above U+007E. Tidy escapes the URI for you as recommended by
HTML 4.01 section B.2.1 and XML 1.0 section 4.2.2. Some user agents
use another algorithm to escape such URIs and some server-sided
scripts depend on that. If you want to depend on that, you must
escape the URI by your own. For more information please refer to
http://www.w3.org/International/O-URL-and-ident.html

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.
