--- Comment #18 from Khaled Hosny <[email protected]> ---
PDF outputs glyphs in visual order, so the original (logical) order of the text
is lost, so the reverse of the bidi algorithm needs to be applied to the text
extracted from the PDF, but there is no reliable or documented algorithm to do
this.
ICU's bidi implementation has modes for applying the reverse of bidi algorithm
(see the last three modes documented in
http://icu-project.org/apiref/icu4c/ubidi_8h.html#afe123acc1196c4d7363f968ca6af6faa),
I have never used them myself but if someone wants to work on this they may
prove to be useful.
