[jira] [Commented] (PDFBOX-2508) Text extraction getting zero font
height, bad widths, and ? for text in this PDF with Type 3 Fonts

Tilman Hausherr commented on PDFBOX-2508:
-----------------------------------------
You definitively won't get any useful text from that file, Adobe can't either.

> Fontsize is way too big (should be more like 8), value for space is ridiculous, height is too small. And each character is coming through as a '?'. The original file has this on every piece of text.
> In Acrobat everything looks fine, both in the original and in this test case.
