History expansions have a similar issue: after running
.
    bindkey ^T f
    (where ^T is a control character, inputted as ^V^T)
.
and then issueing a history expansion
    !!
the ^T is rendered, not as the two characters "^" "T" in reverse video,
but as a literal ^T, which my terminal renders as a box with "0 0 1 6"
inside it (the codepoint).

Printing an easier-to-read representation would be nice, although of
course it's a minor issue.
