'Stiff Opposition Expected to Casketless Funeral Plan'
{$articleTitle|escape:'htmlall'} {* escapes ALL html entities *}
'Stiff Opposition Expected to Casketless Funeral Plan'
<a href="?title={$articleTitle|escape:'url'}">click here</a>
<a
href="?title=%27Stiff%20Opposition%20Expected%20to%20Casketless%20Funeral%20Plan%27">click here</a>
{$articleTitle|escape:'quotes'}
\'Stiff Opposition Expected to Casketless Funeral Plan\'
<a href="mailto:{$EmailAddress|escape:"hex"}">{$EmailAddress|escape:"hexentity"}</a>
{$EmailAddress|escape:'mail'} {* this converts to email to text *}
<a href="mailto:%62%6f%..snip..%65%74">bob..snip..et</a>

<a href="mailto:{$EmailAddress|escape:'hex'}">{$EmailAddress|escape:'mail'}</a>
