[html] How to HTML encode/escape a string? Is there a built-in?

h() is also useful for escaping quotes.

For example, I have a view that generates a link using a text field result[r].thtitle. The text could include single quotes. If I didn't escape result[r].thtitle in the confirm method, the Javascript would break:

<%= link_to_remote "#{result[r].thtitle}", :url=>{ :controller=>:resource,
:action         =>:delete_resourced,
:id     => result[r].id,
:th     => thread,                                                                                                      
:html       =>{:title=> "<= Remove"},                                                       
:confirm    => h("#{result[r].thtitle} will be removed"),                                                   
:method     => :delete %>

&lt;a href="#" onclick="if (confirm('docs: add column &amp;apos;dummy&amp;apos; will be removed')) { new Ajax.Request('/resource/delete_resourced/837?owner=386&amp;th=511', {asynchronous:true, evalScripts:true, method:'delete', parameters:'authenticity_token=' + encodeURIComponent('ou812')}); }; return false;" title="&lt;= Remove">docs: add column 'dummy'</a>

Note: the :html title declaration is magically escaped by Rails.
