Comment 2 for bug 1639542

The thought occurred to me that one will run into this problem in other programs as well, such as Vim. You could work around it on a per-program basis if need be, or if you don't plan on ever using the Shift-Space or Shift+Enter chords, you can simply disable them completely in pangoterm.cfg.

To completely disable any unwanted chord, add the respective line(s) to your $XDG_CONFIG_HOME/pangoterm.cfg:

chord_shift_space = false
chord_shift_enter = false
chord_shift_backspace = false

Note that as of the time of writing, these are the only 3 config options available regarding disabling chords.
