regex for unicode charachters (persian numbers)

Tags: , ,



I have a regex for validating persian date like this:

((((u0661u0663|u0661u0664)[u0660-u0669]{2})(/|-)(u0660[u0660-u0669]{1}|u0661u0661|u0661u0662))(/|-)(u0660[u0661-u0669]{1}|(u0661|u0662)[u0660-u0669]{1}|u0663u0660|u0663u0661))

1.
(u0661u0663|u0661u0664)[u0660-u0669]{2} : only match ۱۳|۱۴ followed by two char between [٠-۹] 
match: ۱۳۹۹ , ۱۴٠٠
not match: ۱۲۹۹
2. 
separator can be / | -
3.
(u0660[u0660-u0669]{1}|u0661u0661|u0661u0662)) : (٠ with following single char between [۱-۹]) | ۱۱ | ۱۲
match: ٠۱ , ٠۹, ۱۱ , ۱۲
not match: ۱۳ , ۲۱ , ٠٠ , etc
4.
(u0660[u0661-u0669]{1}|(u0661|u0662)[u0660-u0669]{1}|u0663u0660|u0663u0661) : match (٠۱-٠۹) |  (۱۱ - ۲۹) | ۳٠ | ۳۱

but testing in this test link does not pass. am I doing any thing wrong?

Answer

thanks to @JvdV, I made a mistake in getting unicode of the persian number characters. the right regex would be:

((((u06F1u06F3|u06F1u06F4)[u06F0-u06F9]{2})(/|-)(u06F0[u06F0-u06F9]{1}|u06F1u06F1|u06F1u06F2))(/|-)(u06F0[u06F1-u06F9]{1}|(u06F1|u06F2)[u06F0-u06F9]{1}|u06F3u06F0|u06F3u06F1))
