Tilman Hausherr updated PDFBOX-5350:
------------------------------------
Attachment: reports_pdfbox_2.0.29_vs_3.0.0.tar.xz
> Regression unicode mapping in Korean document
> ---------------------------------------------
>
> Key: PDFBOX-5350
> URL: https://issues.apache.org/jira/browse/PDFBOX-5350
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.16, 2.0.18, 2.0.20, 2.0.25, 3.0.0 PDFBox
> Reporter: John Mayfield
> Priority: Major
> Labels: regression
> Attachments: KR1019900015076.pdf, KR1019980000128.pdf,
> KR1019980000128_2_0_15.txt, KR1019980000128_2_0_25.txt, KR1020140140600.pdf,
> reports_pdfbox_2.0.29_vs_3.0.0.tar.xz
>
>
> The text output from Korean Patent PDFs changed in v2.0.15+ (due to unicode
> mapping?), this was previously addressed in PDFBOX-4661 and resolved that
> example PDF in v2.0.18 - thanks. Unfortunately v2.0.18 causes other documents
> (included here) to now have incorrect text output.
> PDFTextStripper stripper = new PDFTextStripper();
> PDDocument doc = PDDocument.load(new File("KR1019980000128.pdf"));
> stripper.getText(doc);
> Like in PDFBOX-4661 there are numerous warnings of the form:
> WARNING: No Unicode mapping for CID+14172 (14172) in font GKYPPJ+GulimChe
> I've attached the text dump of two versions, but in brief:
> 2.0.15: 공개번호 (public number)
> 2.0.25: 공개
> I only confirmed the issue in the versions listed above but presume the issue
> persists >=2.0.18.
> My reading of PDFBOX-4661 is there is something funky about these PDFs?
> PDFBOX v2.0.15 had the correct text output. Testing in PDF.js incorrectly
> produces 공개뮈픸 so I can see there is something non-trivial here.
> Any help is much appreciated.
