Jeanne Waldman commented on TRINIDAD-1647:
------------------------------------------
See TRINIDAD-1655 Fix to JIRA-1647 introduced bug where HTMLEscapes._writeText
isn't paying attention to startIndex
This is needed as well for any backporting.

> The HTML specification disallows certain code points from appearing in HTML
> files (XML has essentially the same list, minus the high ISO characters) as
> specified in http://www.w3.org/TR/REC-html40/sgml/sgmldecl.html. The Trinidad
> HtmlEscapes utilities allow the low control characters and the high
> characters that are technically outside of Unicode to be output. This causes
> problems if the content is validated.
> The fix is to use numeric character references such as  rather than
> outputting code point 1 directly. In addition, Internet Explorer has a bug
> where � is output as "�" so it is preferable to suppress this character
> rather then outputting it.
