llvm-rc: Error in VERSIONINFO statement (ID 1): 
Non-ASCII 8-bit codepoint (´┐¢) can't be interpreted in the current codepage 

 

 

This is caused by llvm-rc chokes on cp1252 · Issue #57367 · llvm/llvm-project (github.com)

 

And can be easily fixed by adding these lines to the CMakeLists.txt:

if (WIN32 AND CMAKE_CXX_COMPILER_ID STREQUAL "Clang")
    set(CMAKE_RC_FLAGS="-C 1252")
endif()
