Quotation mark in kernel command line?

[Hexchain Tong]

I'm trying to add something like acpi_osi="!Windows 2012" in kernel comand line, but rEFInd doesn't seem to parse it correctly. Stanzas in $ESP/refind/refind.conf is in use:

menuentry Arch {
    volume XXXX-XX-XX-XXXX
    loader vmlinuz-linux
    initrd initramfs-linux.img
    options "root=/dev/sdaX rw initrd=intel-ucode.img"
    submenuentry "Single user mode" {
        add_options "single"
    }
    submenuentry "Fallback" {
        initrd initramfs-linux-fallback.img
    }
}

I've tried using backslash to escape the quotation mark but no luck. If I put acpi_osi=\"!Windows 2012\" in it, I got acpi_osi=\ for kernel.

How should I correctly escape?

Thanks in advance.

To include a quote mark, double it up, as in:

add_options "acpi_osi=""!Windows 2012"" "

Thanks! Is it better to make it clear in documents?

It is covered in the documentation; see:

Search on quotes. Unfortunately, the topic is an obscure one, so it's ended up buried, and I don't see any way around that aside from over-emphasizing it, which in turn would make other topics harder to find.
