There's a "highlight" plugin that does almost exactly what you describe:

Regex is commonly used for this:

This isn't something that jQuery is generally helpful with--it works more at the node level than the text/html level. However, this might help (source):
$('p:contains(&)').each(function(){
$(this).html(
$(this).html().replace('&','<span class=\'fancy\'>&</span>')
);
});
Obviously if you can restrict the initial search to something better than all paragraphs, it'd perform better. You should also test it to see if the :contains
filter actually helps.
It's not pretty but it seems to work.
