unescapeHTML is a Prototype.js function that uses innerHTML, so not
strictly standards compliant. If that was the goal, the OP would not
be expecting HTML character entities to be parsed when using them as
the content of a textarea element whose content is tyep DOMstring.
For strict standards compliance, plain text should be used and
appended as a DOM text node (e.g. & should be in the text as plain
&).
If the string contains markup and the OP expects it to be parsed, then
either a textarea element is the wrong element to use, or the text
should be parsed first (as occurs with unescapeHTML and innerHTML)
before being used as the content of the textarea.

Nor do I in general, but it does the job here.
