Hebrew search in PDFs is backwards?

[Dov Grobgeld]

You can easily do it with fribidi through the fribidi_log2vis() function.
fribidi is wrapped by pango, but it does not export its API. It does export
pango_log2vis_get_embedding_levels() but you'll have to work a bit more to
use this function.

Dov
