  Well, I was over-optimistic. This patch is related only to  BUG: 207748 & BUG:184399. The other back-ends have many problem not related to this patch as following:
  
  - xps: okular crash when open arabic xps file and if it can open it, it renders it in wrong way.
  - dejuv: searching & copying Arabic text are fine since dejuv back-end has it own search function.
  - odt: there is broken in LTR or RTL. There is no text to search at all.
  - chm: Although okular can open it but searching is bad for LTR & RTL text, it is basically broken.
  
  @aacid the poppler bug  should be fixed, so anybody using QT interface can get the right order for RTL langs.  Okular has its own way to sort words.
