+# Larger Arabic documents currently have non-TeX fonts and XeTeX
+# as default output. To fix pdfTeX export:
+# - set all non-Arab text parts to a different language (e.g. English)
+# - define alternatives for hyperref (e.g. with textorpdfstring)
+# for correct handling of hyperref.
+# - solve problem with ToC:
+# ! This can't happen (copying).
