I use extensions like ultimailto or superemail to encode emails in order
to avoid spam. However they don't work when you put those links
into library object. They work if you put the code alone in the page.
Also accents looks bad showing strange characters.

Is there a better extension? Ultimailto doesn't seems to be supported.

Also I wonder why and how to make those work in library objects
Example of my library object:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<p><a
href="&#109;&#97;&#105;&#108;&#116;&#111;:&#97;&#1 00;&#118;&#101;&#114;&#116;&#105;&#115;&#101;&#64; &#98;&#97;&#114;&#105;&#108;&#111;&#99;&#104;&#101 ;&#46;&#101;&#115;&#112;&#46;&#98;&#114;?Subject=A dvertise%20on%20Bariloche%20esp%20br&body=Please%2 0indicate%20your%20first%20and%20last%20name,%20co mpany,%20phone,%20email,%20webpage%20and%20product %20or%20service%20you%20want%20to%20advertise"><im g
