Define my own reading macro

There are several read macros in Common Lisp, such as ' #' #P, but how can I write a read macro?

Like this:

#T"hello world"
====================>
(gettext "hello world")

You can use set-macro-character and set-dispatch-macro- character , for example, after:

(set-dispatch-macro-character #\# #\T
  (lambda (s c n)
    `(gettext ,(read s t nil t))))
==> T

you can use the set reading syntax

(read-from-string "#T\"this is a test\"")
==> (GETTEXT "this is a test")
