managing comments: lists of comments don't display correctly on comments containing UTF-8 chars

[chrismade]

repro: The list of comments showing at /author/comments.html#moderated and /author/comments.html#approved are not showing UTF-8 chars in comments correctly - this is a minor issue because this is just an internal management list for admins - visitors will not see that issue

I can track down this issue to file ui.apps/src/main/resources/jcr_root/apps/slick/author/comments/list/body.html  where the HTML of the 'list of comments' is created - using HTL and class org.millr.slick.components.common.ListComments but I cannot find any 'response' object to which I could apply     response.setCharacterEncoding("UTF-8");
