I am having difficulty reading UTF-8 encoded text (Sanskrit) from a text file
and writing it onto a PDF page. No text is printed at all when I read from the
file. However, when I simply generate text in the program, it prints as I would
expect. The non-text portions of the page (the lines for the flashcards) print
fine. Also, I am able to do a round trip of reading from the file and writing
to another (text) file in UTF-8 such that I can read it as I expect; I
commented that part out.
I wonder if I am using the correct the correct Font invocations on in my
drawText() method. There seem to be a number of ways to get a font
(FontFactory, Font, BaseFont..) and I am not compeletely positive that i am
doing it the correct way. Any help is appreciated.
