It is very very difficult.  If you understand category codes, you
can manipulate them to temporarily make braces behave differently,
but this will conflict with any need that your macro places on
their normal definition.  Possibly simpler (depending on what you
are really setting out to achieve) is to pass the rather more
complex

{\char \{}

and/or

{\char \{}

but a very great deal depends on what you are trying to accomplish.
