security feature:
"Use '<?~' and it will solve your XSS and other escaping problems with
outputting HTML that was stored in a DB."  What it solves is a subset,
which is escaping characters stored in a data that have special meanings to
HTML. My concern is that the remain security issues might get overlooked or
ignored because '<?~' is considered good enough. There are issues with
htmlspecialchars, UTF-8 and certain language-specific characters (non
English). There were also issues with quotes in the past.
