// form "C:\Users\myusername\Downloads\& curl 172.21.93.52".
// `create-react-app` used a safe file name pattern to validate user-provided file names:
// - https://github.com/facebook/create-react-app/pull/4866
// - https://github.com/facebook/create-react-app/pull/5431
// But that's not a viable solution for this package because
// it's depended on by so many meta frameworks that heavily rely on
// special characters in file names for filesystem-based routing.
// We need to at least:
// - Support `+` because it's used in SvelteKit and Vike
// - Support `$` because it's used in Remix
// - Support `(` and `)` because they are used in Analog, SolidStart, and Vike
// - Support `@` because it's used in Vike
// - Support `[` and `]` because they are widely used for [slug]
// So here we choose to use `^` to escape special characters instead.
// According to https://ss64.com/nt/syntax-esc.html,
// we can use `^` to escape `&`, `<`, `>`, `|`, `%`, and `^`
