It must be a conhost bug of some kind eating characters when interfacing with cbwin.

I see. Actually I noticed that already but I don't know enough about ptys and conhost, and for now I still haven't had time to dig into it. In the conhost case, cmd is not redirected so it uses the Win32 console API. However, some characters also seem to be directed to WSL. There might be something standard to try on either side to improve the situation, but it's only a supposition -- well, I would even try something non-documented on this topic (if not too complicated), would I find one, if it gets the behavior fixed. In the other case, cmd is fully redirected, so it works like when you pipe its input and output. You get basic line edition (delete works, I think) thanks to the cooked input mode on the WSL side.
