here is the patch, and I expained the root cause of this issue in comment:
https://github.com/cjacker/patches/blob/master/fbterm-ctrl-space-toggle-im-two-weird-char.patch

the implementation of toggleActive and setRawMode in fbterm is not so good, rewriting this two functions should be a better way to fix it.
