Dear Maintainer,

in several pdf-viewers using libpoppler certain .pdf-files are not displayed
correctly.

One example ist the file: http://www.ti.com/lit/ds/slis144a/slis144a.pdf

Open it with the integrated .pdf-viewer of iceweasel and it displays correct.

At page 5 the item "I LKG Terminal leakage current" is displayed as 1 µA, the
same item in several .pdf-viewers is displayed without the µ, so it is
displayed as 1 A.

I tested, using KDE, the following viewers and all of them had the same
problem:
Okular, GIMP (selecting page 5), xpdf, vprerex, Druckvorschau, qpdfview,
Dokumentenbetrachter (Evince). So I suppose that the problem is the common
library libpoppler.

Image Magic renders the text correctly (but white on black).

When the .pdf-file is converted to ps with pdf2ps the .ps displays correctly.

When the critical area is selected in okular, the selected text shows the
correct µA.
