Im trying to figure out if I need to raise this as a bug, if this is expected behaviour (and is documented), or if Im just going insane.

After creating a basic api route such as the following
api/users/search/[query]/route.ts

import { NextRequest, NextResponse } from "next/server";

export async function GET(
  req: NextRequest,
  { params }: { params: { query: string } }
) {
  const query = params.query;

  return new NextResponse(JSON.stringify({ queryWas: query }), { status: 200 });
}

And then running npm run dev and navigating to the URL with a valid parameter EG: http://localhost:3000/api/users/search/TestUser the page returns as expected {"queryWas":"TestString"} and nothing is logged in the server console

The issue
When going to http://localhost:3000/search/%F0%9F%93%99 (Encoded Version of 📙) the page still returns as expected {"queryWas":"📙"} ... BUT... in the server console, the following error is printed (https://i.cjcapps.co.uk/2024/02/11/NumbNightheron.jpg) - See Attachment.

What have you tried?
I've tried all I can think of, encoding the emoji, not encoding the emoji, trying to catch it on the route handler. The cause seems to be in (https://i.cjcapps.co.uk/2024/02/11/IllustriousLeafbird.jpg - See Attachment) as if I remove the decodeURIComponent the error seems to stop, although im sure this would cause other issues...

Version?
Im currently experiencing this on 14.1.0 & 14.1.1-canary.47.

Any ideas would be great, or if a bug report needs creating I will start making a standalone repo for reproduction, but I am hoping someone here knows the answer! Thanks!
