Issue description

As far as I can tell, no combination of plainify, safeHTML, markdownify, or html{Une,E}scape can fully remove soft hyphens, and at best converts them to \uad, the only exception I found being anchorize which does successfully remove them.

I'm not sure which functions out of the above should be able to remove soft hyphens or not (my guess would be plainify, since it's meant to "strip HTML tags"), but for now, using replace .Var "­" "" is the only way other than anchorize that I've found.
