Thomas Fischer updated PDFBOX-970:
----------------------------------
Attachment: Test2.pdf
Test2-1.6.txt
Test2.1.4.txt
I put a file icu-4.0.1.jar into my classpath and that essentially resolved the
umlaut issue, they are now represented as combined characters (I'm not quite
sure what search engines do with those). Nevertheless, pdfbox 1.4 didn't need
the additional icu, was the need introduced in a recent version change?
Unfortunately there are still some strange problems with the conversion,
essentially missing characters. I upload a new test file and conversions using
pdfbox 1.4 and 1.6 respectively; comparison shows the errors (and some
additional differences).
