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 on your own. For more information please refer to https://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 https://www.w3.org/WAI/GL.
