Andreas Lehmk=C3=BChler commented on PDFBOX-62:
------------------------------------------

The missing width values are now extracted from the true type font directly=
. I've added the changes in revision http://svn.apache.org/r1600761 to the =
trunk.
I'm going to merge the changes to the 1.8 branch soon.
