speakup and ligatures

[Zachary Kline]

Hi All,
I've begun reading tutorials and information on the LaTeX typesetting 
system.  Many of these are in the form of PDF files, which edbrowse quite 
readily converts and displays for me.
Quite often, these PDFs were prepared by LaTeX itself.  The system has a 
habbit of inserting ligatures whenever common letter combinations are 
used.  These are rendered in utf-8, I believe.  Speakup reads them all as 
"null".  They should rather be read as the combination they are, such as 
"fi" or "ff".  Is there any file I can modify to get speakup to read these 
properly?  It isn't too much trouble for me to figure out from context 
what they are, but it'd be wonderful if Speakup could just do the right 
thing in these situations.
Thanks much for any advice,
Zack.
