It didn't solve the problem, still got the /utf8 error

gcc or clang?

[dg0yt]

-isystem C:/vcpkg/installed/x64-windows/include

This error is for triplet x64-windows which is a triplet for MSVC.

gcc or clang?

With gcc

I have encountered the same problem. When I tried to use clang-cl instead, another problem arised.
cl.exe works well, but that's not what I expected. I want to use clang.

[dg0yt]

AFAICT there is no triplet here for non-mingw Windows clang, regardless of frontend.

[ysyecust]

Is there a plan to fix this issue, my current solution is to switch to 77dfbee: [spdlog] update to 1.15.0 (#42076) before this commit
