Bug 214546 – Intl NumberFormat style currency incorrect format for 'es-CA' CAD

• Component: WebCore JavaScript
• Status: RESOLVED WONTFIX

[Illia Bilichenko]

Facing different results of currency format for locale 'es-CA' and CAD currency.

In Chrome(84.0.4147.89) and Firefox(78.0.2):
Intl.NumberFormat("es-CA", { style: 'currency', currency: "CAD" }).format(100.0) --> "100,00 CA$"

In Safari(14.0) & Webkit build(r264591):
Intl.NumberFormat("es-CA", { style: 'currency', currency: "CAD" }).format(100.0) --> "$110.00"

Unfortunately, I can't find any specification how it showed be formated. Is it expected behavior?

I have a similar situation with 
Intl.NumberFormat('fr-US', { style: 'currency', currency: 'USD' }).format(99999999)

Chrome (84.0.4147.89) and Firefox (78.0.2)  --> "99 999 999,00 $US"
Safari (Version 13.1.2 (15609.3.5.1.3) --> "99999999,00 $US"

Intl.NumberFormat problem

But something interesting happens when I'm trying to select or copy/paste value.

Yes, both are right and expected behaviors because CAD's code is $.

Strictly speaking, this is not WebKit's issue. They are bugs in ICU (https://github.com/unicode-org/icu).
Firefox and Chrome are bundling the latest ICU. Safari is using ICU which is installed in the system (macOS etc.).
If you upgrade the system, you will see the updated behavior in Safari.

I've tested these things with ToT JavaScriptCore with Big Sur beta 3 and ensured that they are now fixed because ICU is updated by the system update.
