If you see image is good, the find result in English appear is harmonic , but in Arabic the speech appears inconsistent because the find result are from left to right, knowing that I use the program in Arabic. If you look at the line in which Arabic is good, you will find a big difference between the line above and the one in the find result, but in English it appears correct .

This is not a mixture between Arabic and English, but what is in the picture to clarify the difference between Arabic and English, nothing more. regex returns false results because it reads words in the wrong direction. It does not seem but this is what actually happens that the search result is in Arabic with wrong word order, in addition to that the sentence is nested then you write half in the correct direction (rtl).

I use Notepad to search files of 80,000 lines and more in Arabic. But the find result appear illegible because the line appears from left to right, not the other way around
I hope I clarified the problem well .
