Leonardo Uribe commented on MYFACES-3744:
-----------------------------------------
According to this link from W3C:
http://www.w3.org/International/questions/qa-controls
control characters should be ignored.
Also this link:
http://www.w3.org/MarkUp/html3/specialchars.html
Says the only valid characters are HT, LF, CR (0x09, 0x0A, 0x0D) and:
"... In HTML, there are only three control characters which are used. The
remaining 55 control characters are shunned and should not appear in an HTML
document. ..."
HtmlResponseWriterImpl should honor that in those places where html escaping is
done, like in writeText or writeAttribute.
> Vertical tab character (\u000B) destroys AJAX-response
