Vite creates an unexpected directory when building in version 7.2.0 and 7.2.1

[luckasnix]

Describe the bug

When generating a production build using Vite 7.2.0 or 7.2.1, an unexpected directory is created. This issue did not occur in previous Vite versions.

It seems to happen when the project is located in a directory whose name contains characters outside the English alphabet.

I tested it with React Router Framework and Tanstack React Start. The bug appeared in both.

@luckasnix Please write the output of npx envinfo --system --npmPackages '{vite,@vitejs/*,rollup}' --binaries --browsers.

I'm wondering if this is related to #21019 and nodejs/node#58768
