Description

wp_kses_normalize_entities() allows a user to type "" in a comment. This is not properly escaped as "". For bloggers outputting true XHTML, this is disastrous. kses should be modified to escape the ampersand in any numeric entity reference that is not a valid Unicode character.

Docs: Expand valid_unicode function documentation.

The valid_unicode() function accepts a limited set of codepoints according to the XML specification. Document the allowed codepoints and link to relevant documentation.
