Description

Hi
I am following the Nextjs 13, client component translations.

My url is something like this http://localhost:3000/en?token=e8dcef6d

Its works fine since i follow the example my app support en and de

but the problem is when the url goes into something like this, unsupported language. Eg (fr)

http://localhost:3000/fr?token=e8dcef6d

its completely break the translations.

Mandatory reproduction URL (CodeSandbox or GitHub repository)

You can implement this by replacing notFound with redirect, right?

Please note that this is not a bug but a usage question, I'm converting this to a discussion.
