OSC returning \e\\ instead of \a

[scandum]

When I echo: \e]4;1;?\a

xterm returns: \e]4;1;rgb:bfbf/0000/0000\a

mintty returns: \e]4;1;rgb:bfbf/0000/0000\e\

Going by the xterm documentation xterm's behavior is as described:

      XTerm accepts either BEL  or ST  for terminating OSC
      sequences, and when returning information, uses the same ter-
      minator used in a query.

Thanks, works like a charm.
