I want to detect duplicate persian words by regex. I have seen examples with english words, but they did not work with persian words. Something like this : \b(\w+)\b, this works with english, but does not work with persian characters.

I want to detect آران in آران وبيدگل آران و بيدگل.

Any idea ?

Are you sure `'/\b(\w+)\b(?=.*\b\1\b)/u'` does not work? – Wiktor Stribiżew Jun 27 '20 at 12:45
@WiktorStribiżew, I totally forgot to use the unicode flag. That's what OP should be after =) – JvdV Jun 27 '20 at 12:52
@JvdV `((?<=^|\p{Z})\p{L}+(?=$|\p{Z})).*\1` won't work because you are not matching diacritics with `\p{L}` and `(?<=^|\p{Z})` / `(?=$|\p{Z})` only matches whitespace boundaries. – Wiktor Stribiżew Jun 27 '20 at 13:12
Yes, so it is a duplicate of two other threads combined. The links are on top. – Wiktor Stribiżew Jun 27 '20 at 13:20
Should I delete my question ? – amir22 Jun 27 '20 at 13:22
