Can you post a screenshot of how Acrobat renders PDFBOX-2642-277053-p3.pdf on
your system? I have Optima installed, so it all looks fine. (Though I can
reproduce the PDFBox issue by hardcoding ArialUnicodeMS).
ACTUALLY: forget it, that PDF has a bad embedded font which Acrobat can recover
but we can't. So it should render fine for both of us in Acrobat.
I've attached PDFBOX-2642-HACK.pdf which is a modified version where the font
name has been changed to FAILED-Bold and the FontFile3 has been renamed to
FailFile3, to prevent Acrobat from loading the embedded font or finding a good
substitute.
On my system, Acrobat refuses to render text the HACK file and just shows
bullet points.

> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.2, 2.0.3, 2.1.0
> Reporter: Tilman Hausherr
> Attachments: PDFBOX-2642-HACK.pdf, PDFBOX_3457.patch, PDFJS-5550.pdf,

> Fonts rendered in wrong size. The cause is related to wrong values in the
> /WIDTHS table and this code in PageDrawer:
> {code}
> // stretch non-embedded glyph if it does not match the width
> contained in the PDF
> if (!font.isEmbedded())
> {
> float fontWidth = font.getWidthFromFont(code);
> if (fontWidth > 0 && // ignore spaces
> Math.abs(fontWidth - displacement.getX() * 1000) >
> 0.0001)
> {
> float pdfWidth = displacement.getX() * 1000;
> at.scale(pdfWidth / fontWidth, 1);
> }
> }
> {code}
> I suspect that there must be another condition to skip the stretching, but I
> didn't find out which one.
