23688	esc_textarea, wp_richedit_pre and wp_htmledit_pre eat post content under PHP 5.4	westi	westi	"Because of a change in default behaviour in {{{htmlspecialchars}}} in PHP5.4 it is possible for these three functions to eat perfectly valid post content and make it impossible to edit existing posts.

Scenario:
 * blog_charset is ISO-8859-1
 * Post contains some 8bit characters

You try and edit the post and instead of the post content you are presented with a blank editor :(

On the front end the posts display fine.

The underlying cause it this change in {{{htmlspecialchars}}}

""5.4.0 	The default value for the encoding parameter was changed to UTF-8.""

Because the string is not a valid UTF-8 sequence an empty string is returned :(
