Describe the bug
In Node.js, we can import ~.mjs with a path like import('file:///path/to/%7E.mjs'). In Vitest, on the other hand, it causes an error.
Also, Errors are caused by any URL-encoded filename other than ~.mjs, such as |.mjs.
Reproduction
⚠️ WARNING: This reproduction depends on the behavior of nodejs/node#54545. You need Node.js v22.12.0+ or v23.1.0+ to reproduce the problem.
