encoding - Necessary to encode characters in HTML links? -

-

should encoding characters contained within url?

example:

<a href="http://google.com?topicid=1&pageid=1">some link using &</a>

or

<a href="http://google.com?topicid=1&amp;pageid=1">some link using &amp;</a>

yes.

in html (including xhtml , html5, far know), attribute values , tag content should encoded:

authors should use "&amp;" in attribute values since character references allowed within cdata attribute values.
