[XeTeX] Trouble with XeLaTeX and Jurabib

[Stuart Robertson]

Dear list members,

I'm trying to typeset an article with XeLaTeX and Jurabib and have  
run into a problem with errant quotation marks. In the example below  
the first single quotation that prefaces the article title remains  
the usual TeX Grave or  ` mark rather than becoming a single opening  
quote or ‘.

I don't know what to do. I've checked the encoding of the files  
involved and varying them makes no difference. I've set the same  
sources with conventional LaTeX and it works fine.

Is this a XeLaTeX problem or a Jurabib one? I'm guessing that it's  
something set in the Jurabib configuration but want to check here  
before posting on the Jurabib list.

Apologies if this isn't clear or if I've not offered enough info.  
Though I'm proficient in using LaTeX I mostly don't understand the  
underlying processes. I can only use LaTeX at all because of the good  
work of Richard Koch, Gerben Wierda, Jonathan Kew and all the other  
people who write and publish packages.

Yours in confusion,

Stuart
