باسلام

احتراما جهت تست 1395/06/28 و         اعداد1/23/3/00000 و اعداد 1،2،3

it not match

but if i press enter it will match

باسلام

احتراما جهت تست 1395/06/28 و      
اعداد1/23/3/00000 و اعداد 1،2،3

Where are you typing the text? Is it a regex matching website? – Nehal J Wani Sep 18 '16 at 05:02
Is the Arabic text right-to-left? I suspect the website doesn't understand that when highlighting the matches. The regexp looks fine. – Barmar Sep 18 '16 at 05:03

Perhaps this question may help http://stackoverflow.com/questions/280712/javascript-unicode-regexes. Probably your problem is doing unicode regex matches using a regex engine that only understands ASCII – Ed Heal Sep 18 '16 at 05:04
@Nehal J Want Yes it is http://regexr.com/ – Mahdi_Nine Sep 18 '16 at 05:05
@Mahdi_Nine Do you see the same behaviour on regex101.com ? – Nehal J Wani Sep 18 '16 at 05:07
@NehalJWani regex101.com has only one match for 1395/06/28 – Mahdi_Nine Sep 18 '16 at 05:12
@Mahdi_Nine Share link to the saved regex on regex101.com – Nehal J Wani Sep 18 '16 at 05:17

@Mahdi_Nine You didn't specify /g . See this: https://regex101.com/r/gV6cV4/2 – Nehal J Wani Sep 18 '16 at 05:38
@NehalJWani it's ok with your link but not work on http://regexr.com/ and my webiste! – Mahdi_Nine Sep 18 '16 at 06:58
@EdHeal the regex works fine on regex101 in JS mode. OP needs to show his JS code. – Lucas Trzesniewski Sep 18 '16 at 09:04
@LucasTrzesniewski - i concur - Perhaps he(?) is not saving it as unicode – Ed Heal Sep 18 '16 at 09:05

Don't rely on how regexr.com highlighting works. Online testers have some issues with highlighting matches against Unicode characters. If you enclose your RegEx in capturing groups `((\d{1,30}\/)+\d{0,30})` you'll see correct values are matched and captured. – revo Sep 18 '16 at 09:13
