issue with control characters appearing in command window

[manbearian]

suddenly my command window starting show control characters instead of doing the actions (e.g. image shows pushing the up arrow on the keyboard and then the down arrow). Other shells/tabs in the same terminal window don't have this issue.

Unfortunately i don't have a repro, and i don't know how i got into this state. I have a DMP of WIndowsTerminal.exe if that helps.

So, this is usually caused by an application leaving ENABLE_VIRTUAL_TERMINAL_INPUT enabled when it exits. The input state is, unfortunately, global for a given console session (in Terminal, that's the tree of processes under one terminal pane)... which means applications can trivially mess with eachother like this.

thanks for the quick response; is there an manual fix i can run? i'd love to save this terminal session :)

Hmm.. so, if you just run powershell and then exit it, it should restore the input mode. I just gave that a shot over here.

Btw, now that i can get my history for that shell, i believe that the culprit is vi. the last few previous commands were git diff invocations.

Thanks for that! Yeah, it'll do that sometimes. Sorry 😄

For this one, by-design is appropriate, even though that's a little unfortunate. We're kicking around the idea of making the input mode per-process state, but our input queue is appalling right now. I tried to hack this up for hackathon!
