I'm getting an error extracting text from a PDF using iText 5.1.3. It
works fine with PDFs that use Roman characters, fails on Japanese and
Korean documents. I searched the forums and found something similar, but
not with the same error call stack, so I'm posting it.
I can post the PDF, but would have to clean off any sensitive data in it
first. If I can send it to just a few people instead of posting it
publicly, it would be easier.
