//! Build script for arf-console
//!
//! On Windows, this embeds an Application Manifest that enables UTF-8 support
//! for R 4.2.0 UCRT builds. Without this manifest, embedded R uses the system's
//! ANSI code page (e.g., CP932 for Japanese Windows), causing encoding issues.
//!
//! This approach is based on ark's build script:
//! <https://github.com/posit-dev/ark/blob/main/crates/ark/build.rs>
