Is there a way to get these escapes (http://www.evotech.net/blog/2007/04/named-html-entities-in-numeric-order) working in custom CSS? I've noticed that the backslash+number notation works if I use two backslashes and I suspect this is a parsing issue. I had this working at one point (months/years ago) so I suspect this is a bug.
Thanks for your help!
