Neil McErlean updated PDFBOX-903:
---------------------------------
Attachment: TestUnicodeText.java
I've made some progress on this issue and have verified it's not an issue with
COSString (see PDFBOX-904).
Here's a work-in-progress test case (an update to Nick Burch's) that reproduces
the issue.
I'm still looking at this issue. It looks like the problem is underneath
ShowText.java, which reads the correct String from the COSString instance, but
passes its byte[] to processEncodedText(byte[]) thus losing its encoding.
> Unicode text getting mangled via TextToPDF + PDFTextStripper

> Key: PDFBOX-903
> URL: https://issues.apache.org/jira/browse/PDFBOX-903
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.4.0
> Reporter: Nick Burch
> Attachments: TestUnicodeText.java, TestUnicodeText.java

>
> I'm trying to round trip some text through PDFBox, but I'm finding that along
> the way unicode text is getting mangled and coming back as the wrong
> characters.
> The process I'm following is to use TextToPDF to generate a PDF, then reading
> it back in again with PDFTextStripper. I'm not sure if the problem is coming
> about during generation or reading yet, but I've a nasty feeling there might
> be an issue with both. (I've seen issues with code that does one part of the
> other)
> Attached is a unit test written against trunk. It creates a series of Reader
> objects based on both ASCII and non-ASCII text, creates a PDF using
> TextToPDF, then compares the text. It includes a test that verifies that the
> corruption isn't caused by the readers, and another that fails showing that
> the text was corrupted by the roundtrip.
> Ideally the test would also look in the dictionary to check what was stored
> there, but I don't know enough about the file format to manage that. Will
> hopefully look into that shortly though.
