How to pass argument of hex string in the form of "x" in vscode, launch.json

I noticed that in vscode, if I specify "\xD0\x00" in launch.json like so, the backslash gets removed, and the argument ends up becoming like "xD0x00".

If the argument is in the form of "xD0x00", it ends up becoming like "D000".

How do I pass the argument so that it gets picked up as "xD0x00"?

    "configurations": [
        {
            "name": "gcc.exe - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\${fileBasenameNoExtension}",
            "args": [
                "-p",
                "\xD0\x00"                
            ],
