----------------------------------
Summary: U+2225 rendered as U+2016 glyph when use UniJIS-UCS2-H
and non embedded font
Key: PDFBOX-4570
URL: https://issues.apache.org/jira/browse/PDFBOX-4570
Project: PDFBox
Issue Type: Improvement
Components: FontBox
Affects Versions: 2.0.15
Environment: Windows 10 64bit, Adobe Reader 2019.012.20034
Reporter: chunlinyao
Attachments: correct.png, incorrect.png, u2225.pdf
Maybe this is not a bug of PDFBox, This pdf rendered difference than adobe
reader. it use MS PMincho font, this font has glyph for U+2225, the glyph in
Win10 different from WinXP (I confirmed that by using FontForge.)
The Adobe Reader 2019.012.20034 ON Win10 rendered it correctly. Even Adobe
Reader 2019.012.20034 ON macOS rendered incorrect. (with MSPMincho font
installed)
MuPDF 1.6 on Windows, Chrome, FireFox all rendered it like PDFBox.
Although Adobe Reader on win10 rendered it correctly, When you copy the text
from pdf, you will get U+2016 not U+2225.
I doubt Adobe Reader doesn't use UniJIS-UCS2-H to convert unicode to cid then
convert back to unicode when retrive glyphs.
The UniJIS-UCS2-H is obsoleted. It mapping both U+2225 and U+2016 to CID+666,
Change to UniJIS-UTF16-H can workaround this problem.
Is there some posibility to improve PDFBox render like Adobe Reader?
