[XeTeX] footnotes with opentype superscript, and bibtex with xetex (quotes and hyphens)

Hi Will,

Thanks for the quick reply!

I realize this morning (of course) that my lack of sleep last night  
was impairing my judgement of little tiny numbers. xltxtra does use  
OT superscripts. I think I must have had some line of code in the  
wrong place or something, but now I can't reproduce it.

What xltxtra does do is to use the default font, which in my case  
meant it would use old-style numbers. So I did this:

\makeatletter
\def\@makefnmark{{\fontspec{Minion Pro:+sups,-onum}{\@thefnmark}}}
\makeatother

I'm not sure why, but I like the little codes ;-)

Then I used the command \addfontfeatures and found that  
\addfontfeatures{+sups,-onum} doesn't work. So I tried

\makeatletter
\def\@makefnmark{{\addfontfeatures 
{Numbers=Lining,VerticalPosition=Superior}{\@thefnmark}}}
\makeatother

But that produced superscripts strangely with too much space in front:

But using the \fontspec one above works correctly:

I had [Mapping=tex-text], but after the font definitions. Though,  
surely enough, it's listed on the xetex faqs site: ... in order to  
automatically apply this mapping to the subsequent fonts you load.  
Makes perfect sense; just missed it.


And while I'm on the subject of footnotes, I've got another question,  
though maybe not specific to xetex. thefnmark seems to apply to both  
the footnote number in the text and in front of the note. How might I  
make only the numbers in front of the notes non-superscript (and add  
a tad more spacing in between)?


Best,
Alex
