Comment:

 Currently, it's safe to assume that `esc_attr( esc_attr() )` doesn't break
 anything (see comment:7:ticket:20009 for example), which won't be the case
 with double-encoding.


 The issue with saving `©` in the Tagline field seems worth
 investigating. At a glance, however, it doesn't have anything to do with
 `esc_attr()`, as it doesn't escape HTML entities.
