Extracting CJK text
-------------------
Key: PDFBOX-654
URL: https://issues.apache.org/jira/browse/PDFBOX-654
Project: PDFBox
Issue Type: Improvement
Components: Text extraction
Reporter: Atsuo Ishimoto
This is an update for PDFBOX-420 filed by Takashi Komatsubara.
In this patch, if "Identity-H" is used as encoding of font and the font doesn't
supply TO_UNICODE table, then encoding name is generated from CID information
(Registry and Ordering). This idea is borrowed from pdfminer[1], an another PDF
library written in Python. I don't see any test failures with this patch.
I have published this patch last year[2], and got some good feedbacks from
Japanese users[3].
