[Bug]: Non-ASCII object keys cause a syntax error after minification #5591
Description
Reproduction link or steps
What is expected?
Foo・Bar should be wrapped in quotes, I guess.
What is actually happening?
const e={Foo・Bar:`Baz`};export{e as foo};
$ node
Welcome to Node.js v22.17.1.
Type ".help" for more information.
> const e={Foo・Bar:`Baz`};export{e as foo};
const e={Foo・Bar:`Baz`};export{e as foo};
^^^^^^
Uncaught SyntaxError: Unexpected token 'export'

Dunno why envinfo doesn't show the rolldown version, but I tried with both beta.20 and beta.31, same issue.
