how to read ebooks on samsung c 6712
i am using samsung star 2 duos c 6712 mobile. it is capable of reading ebooks in the format fb2 with foliant reader. i am using calibre to convert the books to fb2 format. my problem is that i want to read malayalam (which is a regional language in india) ebook on my device. when i convert malayalam ebook in pdf format i get the fb2 version but with unknown characters. it is because of font problem i think.is there any way to include malayalam fonts in calibre? kindly suggest a way to overcome this problem.
