Tilman Hausherr commented on PDFBOX-4570:
-----------------------------------------
When looking at
[https://www.compart.com/de/unicode/U+2225]
then it is like in PDFBox, i.e. fully vertical.

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

> 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?
