I wanted to create a Bengali document using Latex. I am using MiKTeX 2.9 in windows XP. I installed all the fonts and the packages for MiKTeX 2.9. I copied the code given here and here. Both of them are not working. Both the cases I got following error:
("C:\Program Files\MiKTeX 2.9\tex\latex\fontspec\fontspec.cfg"
! Undefined control sequence.
<argument> \c_keys_code_root_tl
fontspec/Ligatures/Historical
l.8 ...tureoption{Ligatures}{Historic}{Historical}
?
At the end, it is producing a .pdf file but without any content. Could anybody please help me with this?
