/**
* Returns a copy of the string with non-ascii characters replaced by their
* html numeric character reference in decimal (e.g. 〹).
*
*
* The purpose of this is to produce a multipart/formdata submission that
* any server should be able to handle, based on experiments using a modern
* browser (chromium 47.0.2526.106 for mac). What chromium posts depends on
* what it considers the character encoding of the page containing the form,
* and maybe other factors. It would be too complicated to try to simulate
* that behavior in heritrix.
*
*
* Instead what we do is approximately what the browser does when the form
* page is plain ascii. It html-escapes characters outside of the
* latin1/cp1252 range. Characters in the U+0080-U+00FF range are encoded in
* latin1/cp1252. That is the one way that we differ from chromium. We
* html-escape those characters (U+0080-U+00FF) as well. That way the http
* post is plain ascii, and should work regardless of which encoding the
* server expects.
*
*
* N.b. chromium doesn't indicate the encoding of the request in any way (no
* charset in the content-type or anything like that). Also of note is that
* when it considers the form page to be utf-8, it submits in utf-8. That's
* part of the complicated behavior we don't want to try to simulate.
