Description

Attached file is just line one from a file where every piece of text has these problems. All the other lines were removed with Nitro to make a small test case.

This is the output from PrintTextLocations example:

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.
