  default:

flag use-wchar32
  description:
    Use 32-bit for ImWchar (default is 16-bit) to support unicode planes 1-16. (e.g. point beyond 0xFFFF like emoticons, dingbats, symbols, shapes, ancient languages, etc...)
  default:
    True
  manual:
    True

flag use-ImDrawIdx32
  description:
    Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
    Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
    Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
    Read about ImGuiBackendFlags_RendererHasVtxOffset for details.
  default:
    True
  manual:
    True
