Greetings Paolo,
Thanks for your response to my issue. Unfortunately, I am still
unable to get PDF output with CJK characters.
I put the fonts into a subpackage of my project
(org.norvelle.textcite.gui.fonts). I then used the form
BaseFont.createFont("org/norvelle/textcite/gui/fonts/FreeSerif.ttf",
BaseFont.IDENTITY_H, true) to create my a BaseFont object for
FreeSerif, which I then pass to the Font constructor. The output,
unfortunately, still lacks any CJK characters.
I've checked the PDF file make sure it has FreeSerif embedded, and it
comes up as "Embedded subset" with encoding Identity-H. So the font
is being embedded, but the CJK characters still aren't showing up.
I'm baffled at this point... any help will be greatly appreciated.
Cheers,
Erik
