The elisp manual makes it clear that the intended syntax for single
characters is the same in both cases. In "(elisp) Changing Key
Bindings":

       The key definition and lookup functions accept an alternate syntax
    for event types in a key sequence that is a vector: you can use a list
    containing modifier names plus one base event (a character or function
    key name).  For example, ‘(control ?a)’ is equivalent to ‘?\C-a’ and
    ‘(hyper control left)’ is equivalent to ‘C-H-left’.
