[XeTeX] Fontspec problem (OpenType stylistic sets)

[Will Robertson]

Hi Alex,

I've forwarded my reply to the XeTeX list since the reply is relevant  
to everyone using fontspec.

You wrote, paraphrased:

Sorry for the problem here -- this is a known issue (indeed caused  
because I never had a chance to test it!) with an easy fix in the  
source. I don't have a schedule for a new release, but I guess it'd  
be good to get this minor version out sooner rather than later.

To fix the problem, find the appropriate section in fontspec.sty and  
replace it with:

\define at key[zf]{options}{Variant}{%
   \setkeys*[zf at feat]{Variant}{#1}%
   \unless\ifx\XKV at rm\@empty
     \edef\@tempa{\noexpand\zf at make@feature{18}{#1}{+ss\two at digits 
{#1}}}\@tempa
   \fi}

(Search for "\define at key[zf]{options}{Variant}" to find the right spot.)

Thanks for the pointer to the Junicode font, by the way!
I look forward to taking a look at it.

Will
