John Mayfield commented on PDFBOX-5350:
---------------------------------------

Still not working in 3.0.0. I will try and find time to work out what change caused the regression.

> 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.
