cmd.exe spawned from conemu has strange characters
Versions
ConEmu build: 161206 x64/x32 OS version: Windows 10 x64 Used shell version: cmd.exe (10.0.14393.0) or Far (4774 x86)
Problem description
cmd.exe spawned as separate window has some strange characters near drive prompt. It only happens on Windows 10.
Steps to reproduce
- run conemu cmd
- type start /separate cmd.exe
- observe the newly created window
This is also happening when running cmd.exe from Far's command line with Shift-Enter.

Why do you spawn cmd.exe outside of ConEmu? It would be much better to get it in new tab inside ConEmu window.
No particular reason - I just prefer windows managed and accessed by default OS functions over ConEmu's tabs. I also found out that running cmd.exe with "use legacy console" option checked doesn't have this problem.
Why do you use ConEmu? Is suppose to get proper terminal, don't you? Than, why do you run new cmd.exe in legacy console window instead of ConEmu?
Probably because Win+X shortcut opens shell in another tab (I would prefer separate window) and Win+W opens separate window however with Far (as this is my preferred shell). Also with Win+Shift+W I can open separate console but will have to choose proper option from the dialog. Frankly I couldn't figure out how to configure ConEmu to open separate console with Win+W instead of Far. If it's possible I would appreciate help.
Regardless of my habits the problem with strange characters remains.
Did you disable "Multiple consoles in one ConEmu window"?
If so, Win+X shall open new window, if it opens new tab - it's a bug.
I can confirm that the "Multiple consoles in one ConEmu window" is unchecked and Win+X opens new separate console when pressed from conemu cmd. However from Far (I know this is separate project) new console is opened within same window. In Far case, windows taskbar preview however shows two windows.
I also have this problem. To explain the requirement more: Sometimes, I have console tasks that take a long time to process, and I prefer to have them running in the background. The best way to do that with a console application is to have it run in its own Window, that I can minimize away and look at the output later. Clearly I don't want to run these tasks inside FAR because then I cannot use my file manager any more. I have not found a way to launch a cmd.exe process from FAR in ConEmu without having these odd characters appear.
I've had this problem for years. In any of the shells somehow it appears.
For example right now if I press shift + space in a pyhton shell I get 32;2u which makes conemu unusable
