Fix sanitizer with libxml2 >= 2.12.0

Somehow with newer libxml2, `<?xml encoding="UTF-8">` no longer enforces
UTF-8. Instead, non-ASCII contents are treated as ISO-8859-1 and get
broken.

For example, `<p>中文</p>` becomes
`<p>&auml;&cedil;&shy;&aelig;&#150;&#135;</p>` (should be
`<p>&#20013;&#25991;</p>`).

Switching to another trick mentioned on [1] fixes the issue, and the
new trick still works with older libxml2 (tested 2.11.5).

As a side note, DOMDocument::loadHTML uses HTMLParser in libxml2 [2][3].
