I think you could find out how far away we are from that by using
'scribble --latex' and then running xetex on the output file. You may
be lucky and we may be close....

I've ripped off display-protected from latex-render.rkt, removed the latex command syntax escaping (so I can have backslashes, underscores and carets) and every time I have a new unicode character I want to use, I have to add to the big case expression. I then translate all elements before putting them in the exact-chars element. I don't know how to wrap delayed and part-relative elements, but I haven't needed to yet.
