    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:
      String[211.92,356.8801 fs=58.0 xscale=58.0 height=1.75392 space=190528.28 width=1.7052002]?

      String[140.72041,299.28 fs=58.0 xscale=58.0 height=3.31296 space=349985.12 width=3.1667938]?

      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.
