-----------------------------------------
[~fred_andrews] Your title mentions "zero font height", your output text in the
issue doesn't have zero font height, and what I get after the fix is this:

Did you use a modified version at that time? I tried with 1.8.7 (the version
you mentioned) and I get zero height.
With 2.0, the output is:

> 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.
