Originally assigned to: @zadjii-msft on GitHub.

It seems to me that output is line-wrapped by conhost before being sent through the ConPTY stdout pipe. This makes sense, though it has the unfortunate downside that in Alacritty we can't do the line-wrapping ourselves.

This wouldn't matter that much, but when selecting and copying text in Alacritty which has been line-wrapped by conhost, Alacritty isn't aware that the text was originally a single line and inserts a newline into the content placed on the clipboard.

Is it possible to disable the line wrapping by conhost?

(Perhaps this would be something that would naturally be in the "passthrough" mode I've seen mentioned elsewhere in this issue tracker?)
