Bug

When entering a unicode symbol like ° (U+00B0, °, the degree sign) into the description field on the 'Domains' page(admin/groups-domains.php), the symbol is displayed as it's html escape string (°).

Steps to reproduce

1. Go to the domains page (admin/groups-domains.php)
2. Add a new domain where the description contains a °. (alternatively edit an existing one)

Expected Behavior

Like other description fields on the 'groups' or 'clients' pages, the value should not be escaped (these are <input> html elements).

Ah, I just saw that #2279 / #2851 already adress this. I missed those earlier when searching for this. Please forgive me for the spam. Hopefully this at least helps the "SEO" for this problem :).
Thanks for the awesome software btw!
