The doc string of this command is less than comprehensible, IMO.

  Handle inserting of a character other than allowed.
  Display an error on trying to insert a disallowed character.
  Also discard all previous input in the minibuffer.

To me, this doesn't say anything about what this command does.  After
all, it's a _command_, not just a function that reads a char
(presumably).  What does it do - what do you use it for?

What does "handle" mean here?  What are the "allowed" chars, and in what
way are they "allowed"?  What's meant by "previous input" here?
___

A guess is that by discarding "previous input" is meant first clear the
minibuffer - remove its content.  ("Previous input" suggests minibuffer
history.)
