Adobe Reader is much more successful for extracting text e.g. from
http://www.ice.gov/doclib/sevis/pdf/sevis_arabic_fs.pdf (one of the first
results from http://www.google.com/search?q=arabic+ext%3Apdf ). This seems
partially related to dev_text not expecting RtL text and inserting too many
unintended linebreaks, and also due to Unicode normalization divergences.
