Andreas Lehmkühler resolved PDFBOX-654.
---------------------------------------

       Resolution: Fixed
    Fix Version/s: 1.1.0

WOW, that's really a great improvement. I've applied the patch with version 921494. All text extract tests are still working. As a test for the patch I've extracted the text from the document attached to PDFBOX-420. I'm not really able to read the result, but I've just compared the "pictures" from the textfile with those displayed in acrobat and it looks great.

Thanks to  Atsuo for the contribution.

> 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].
