Unicode filesystem paths break iOS precompiled xcframework resolution due to unescaped URI handling #56878

Description

React Native fails to resolve/build precompiled xcframeworks correctly when the project exists inside a filesystem path containing Unicode characters (e.g. emoji or certain non-ASCII characters).

This appears to be caused by unescaped file:// URI handling somewhere in the xcframework resolution/build pipeline.

Expo maintainers confirmed and fixed the issue on their side, but noted the same issue still exists upstream in React Native when built from precompiled xcframeworks. The fix on the Expo side can be found here

Steps to reproduce

1. Create a new React Native / Expo project

npx create-expo-app@latest expo-unicode-path-bug

2. Place the project inside a Unicode filesystem path, for example:

/Users/<user>/💻dev/expo-unicode-path-bug

3. Upgrade/install latest SDK / dependencies

4. Run:

npx expo prebuild --platform ios --clean

or equivalent iOS build flow using precompiled xcframeworks.

5. Observe failure during CocoaPods / xcframework resolution.
