Allow two html tags in node titles How I can allow two html tags &lt;sup&gt; and &lt;sub&gt; in node title of all content types.

Or may be is there some module for BB tags which allow using BB-codes in title?

Or my ba is there some hook for preprocess all titles?
function template_preprocess_node(&amp;$variables) 


makes available in your node.tpl the variable $title, so you can wrap this as you like in your node.tpl theme file.
