stripper() function doesn't remove HTML entities

[cameroncooke]

Given the following HTML string <b>Tea &amp; coffee</b>:

when rendered we get:
"Tea & coffee"

when calling the stripper() method and rendered we get:
"Tea & coffee"

I would expect the HTML entities to be decoded, so when rendered:
"Tea & coffee"

I can't see any use case where I would want an NSAttributedString that has been stripped of HTML formatting to show HTML entities which are by definition HTML.
