(1) Open console (2) Run `new Intl.NumberFormat("ar-AE", {useGrouping: false}).format(9876543210)` What is the expected result? "٩٨٧٦٥٤٣٢١٠" What happens instead? "9876543210" See https://github.com/unicode-org/cldr/blob/master/common/main/ar_AE.xml#L42 1701253 1 ap 2020-10-24 12:13:49 -0700 This is an intentional choice in Apple's ICU (for Apple employees, see rdar://problem/45142422&21778421). Rob, are you reporting this as simply a mismatch with CLDR, or does this cause issues? 1701539 2 rsnow 2020-10-26 11:06:02 -0700 Can you explain more of why this is an intentional choice? (for us non-Apple folk) We are relying on CLDR to handle number formatting and it's appearing differently between the browsers. This is problematic because I need to parse numbers as well, for which I also rely on CLDR because the Intl object doesn't have a corresponding number parser. I'd prefer to not have Safari specific code to override this. It certainly causes a loss of faith as well because I don't know how many more of these intentional differences exist. It also means it's harder for me to write unit tests for because Node uses CLDR as well. 1775940 3 ysuzuki 2021-07-09 01:13:31 -0700 Anyway, Intl feature is not ensuring the underlying data, and it depends on the implementation. Please report the feedback against Apple radar since this is the intension in AppleICU, not WebKit ;) 1775941 4 webkit-bug-importer 2021-07-09 01:22:23 -0700 <rdar://problem/80365345> 1837240 5 ysuzuki 2022-02-03 20:39:59 -0800 It is now upstreamed to CLDR :) https://github.com/unicode-org/cldr/commit/c601fc4fd1321f6af4a5f9ae67f4f198305e5c63 1837250 6 mmaxfield 2022-02-03 21:20:44 -0800 is "WONTFIX" really the right resolution? If the bug report is "Intl.NumberFormat formats ar-AE numbers differently from other browsers" then a legit solution is "make the other browsers match WebKit." Seems like MOVED would be a better resolution. 1837252 7 ysuzuki 2022-02-03 21:38:35 -0800 Sounds good. Changed it to MOVED.
