[Users] HTML Support within Claws-mail

[Brian]

I understand that claws-mail is intended for text not HTML, but some of
my subscribed sites don't offer text only (example FORMED
<parishcare at formed.org>). So I installed the Fancy plugin
and allowed remote content, images, java script, and plugins. However I
find that some websites still don't render and instead I end up with a
blank preview box. Currently don't have firewall or antimalware
running.  

Is there something I'm forgetting to do, or is Fancy not expected to
convert all HTML?

It seems the ones encoded with UTF-8 although they are 
multi-part message in MIME format, always fail.  Is this an issue with
my webkitgtk build or an issue that fancy only allows 7-bit?

Cheers, Brian
