manual set ipdb shell to vi mode work in linux but escape char wrong in windows

[WillDawnlll]

i add one line in ipdb main.py _get_debugger_cls to use command vi mode when debug ipdb.set_trace, and this work good in linux

def _get_debugger_cls():
    shell = get_ipython()
    #shell=None
    if shell is None:
        # Not inside IPython
        # Build a terminal app in order to force ipython to load the
        # configuration
        ipapp = TerminalIPythonApp()
        # Avoid output (banner, prints)
        ipapp.interact = False
        ipapp.initialize(["--no-term-title"])
        shell = ipapp.shell


######################add line
        shell.editing_mode='vi'
    else:

but when i do same thing in windows , vi mode prompt broke, and print some char like ?[6 qipdb> list?[2 q?[2 ?[2 q it look like some cursor control escape char i think.... and this both happen in cmd and powershell , but when create cmd in ConEmu , ipdb vi mode work great is there some config i set wrong ? or other nomal way to config vi mode in ipdb?

ipdb is a light wrapper around the IPython debugger.

You should ask this question on IPython repository.
