Those are good points. A couple of questions:
- Do we change the display for the space character as well?
We could display it as ?\s, or leave it as " ", which makes the
character widget appear empty, when it's not.
- What do we do with the other escape sequences, like ?\r and ?\f?
Right now, we display those as ^M and ^L respectively. If we keep this
representation, maybe somebody will feel there is some inconsistency,
because some characters we display as ^M, while others as \n. Perhaps
is not a big deal, though.
