Document using japanese characters returns 401 on GET using in-memory storage

Environment

• Server version: 7.0.5
• Node.js version: v18.20.2
• npm version: 10.5.0

Description

Documents containing Japanese characters return a 401 on a GET request. In particular, this only seems to happen using the in-memory storage (with the default configuration).

I'm pretty sure it's a problem with the server, and not the authentication library, because running the exact same code without using Japanese characters it works properly. It also works properly if I use file storage (with @css:config/file.json).

It's also not something that "only happens in my machine", because I've reproduced the error in CI as well. You can find a minimal reproduction here, with the problem replicated using Cypress: https://github.com/NoelDeMartin/reproductions/tree/css-encoding-401
