No. Only the first character of each component of a dbus object path
gets escaped like that, if it is a number (or actually any character
outside of a-zA-Z). hence:

         foo → foo
        foo3 → foo3
        3foo → _33foo
       3foo3 → _33foo3
           3 → _33
          10 → _310

And so on...
