I'm not sure I understand: it sounds like you are saying that M-SPC
doesn't work in xterm, either? (Which version of xterm. btw?) So the
question now becomes: how did it work before that change in wezterm
for you, and why did modifyOtherKeys feature broke it?
Which terminal file in lisp/term/ was/is Emacs loading at startup when
you use wezterm?
