Keep simsun.ttc ahead of simkai.ttf. When higher-priority CJK fonts are ineligible, select_font assigns both fonts the same fallback score and selects the first registered font. The current order can therefore switch affected glyphs from SimSun to KaiTi.

In `@minipdf-rs/crates/minipdf-cli/src/main.rs` at line 317, Update the font
registration order near simkai.ttf so simsun.ttc remains listed before
simkai.ttf. Preserve this ordering because select_font uses registration order
to break equal fallback scores and must prefer SimSun over KaiTi.

windows-sys 0.61.2 Win32_Graphics_Gdi feature Win32_Foundation RECT

💡 Result:

In the windows-sys 0.61.2 crate, the RECT struct is not located under the Win32_Graphics_Gdi feature [1][2]. Instead, it is defined in the Win32_Foundation module [1]. To use the RECT struct in your project, you must enable the Win32_Foundation feature in your Cargo.toml file: [dependencies.windows-sys] version = "0.61.2" features = [ "Win32_Foundation", ] Once this feature is enabled, you can access the struct in your Rust code via: use windows_sys::Win32::Foundation::RECT; While many GDI functions (such as FrameRect or CreateRectRgn) accept or return rectangles [3][4], the RECT type definition itself remains centralized in the Foundation module to allow for consistent usage across different Windows API subsystems (like UI or Graphics) without requiring unnecessary feature bloat [1][5].

Citations:

Enable the windows-sys Foundation feature. windows_sys::Win32::Foundation::RECT requires Win32_Foundation, but the manifest enables only Win32_Graphics_Gdi; a Windows build can therefore fail to compile xlsx.rs. Add Win32_Foundation and compile this crate in Windows CI.
