Hi @marqgonz, I am afraid that Multipass support for Windows starts on Windows 10. The windows console infrastructure was not able to deal with that sort of thing in Windows 8. They reworked it extensively in Windows 10 and I don’t expect they’d port it back. This series of blog posts has more info on that if you’re interested.
That said, you may be able to get rid of those symbols by doing export TERM=xterm-mono, but many other aspects are different now (e.g. encoding, history, scrolling, wrapping) so you may run into more trouble.
