Is static error pages with locale support not supported for pages router?

[cupofjoakim]

Hi!

We're trying to migrate our app using pages router to next-intl before we start moving over to the app router. We have up until this point relied on nextjs's own i18n config.

One feature that we're struggling to figure out is static page generation on 404's and 500's with locale support. The documentation is very app-router centric, and the examples don't really cover i18n in error pages.

As a base question: Can we somehow statically generate error pages with locales in the pages router using next-intl?

If not, can we do it in the app router while still triggering them from the pages router? i.e. a 500 is thrown from a pages route, resulting in the app router error page to show?

I've just added a 404 page to the Pages Router example in #2062 and didn't really encounter any issues.

Can you elaborate on what exactly the issue is that you're seeing? A minimal reproduction might help.
