Tilman Hausherr commented on PDFBOX-4570:
-----------------------------------------
I found out that I have two MSPincho fonts on my W7 system. One ttf file from
1998, and one ttc file that is much newer. The old file has vertical lines, the
new one has diagonal lines.
> U+2225 rendered as U+2016 glyph when use UniJIS-UCS2-H and non embedded font

> Project: PDFBox
> Issue Type: Improvement
> Components: FontBox
> Affects Versions: 2.0.15
> Environment: Windows 10 64bit, Adobe Reader 2019.012.20034

> Priority: Minor

> 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?
