bool isWindows = new[] {PlatformID.Win32NT, PlatformID.Win32S, PlatformID.Win32Windows, PlatformID.WinCE}
    .Any(p => Environment.OSVersion.Platform == p);

// The FontConfigSubstitutionRule object works differently on Windows/non-Windows platforms.
// On Windows, it is unavailable.
if (isWindows)

    Assert.False(fontConfigSubstitution.Enabled);
    Assert.False(fontConfigSubstitution.IsFontConfigAvailable());
}

bool isLinuxOrMac =
    new[] {PlatformID.Unix, PlatformID.MacOSX}.Any(p => Environment.OSVersion.Platform == p);

// On Linux/Mac, we will have access to it, and will be able to perform operations.

    Assert.True(fontConfigSubstitution.IsFontConfigAvailable());
