long story short, i want add this character
ـ
explanation ..
in arabic their is a character called "kashida" and this is it " ـ " it may looks like underscore in some fonts but it's different one
kashida is cosmetic character in arabic that doesn't affect the words, not the spelling not the meaning not the phonetic, nothing at all, it only used to stretch the words for just justifying the lines and paragraphs.
here is an image for a word with and without kashida and they are absolutely the same, just with different number of characters ..
the first word is only 5 characters
the second one is the same as the first one by all means but it's 15 characters with 10 kashidas in the middle
and this makes the search treat them as different words although they are the same
you can find more info about kashida in this wiki link ..
https://en.wikipedia.org/wiki/Kashida
i can't ask to treat the kashida " ـ " as a diacritics by default as other people may not see it like that ..
but for me i want to have the option to ignore it, and i will in 99% of the times, unless i wanna find it itself..
thank you.
