It is Apache server, and it could be a problem as
.lisp scripts are automatically run on my system
through binfmt_misc file system by clisp.

I have no variable *socket-connection*

It is just plain file, with one Unicode character
inside.

Then I found out if I don't use automatic
invocation of CLISP for .lisp files, and run the
encoding.cgi file like this below it will not
work:

#!/usr/bin/clisp
;; (setf custom:*default-file-encoding* "utf-8")
;; (setf custom:*misc-encoding* "utf-8")
;; (setf custom:*terminal-encoding* "utf-8")
;; (setf custom:*pathname-encoding* "utf-8")
;; (setf custom:*foreign-encoding* "utf-8")

(defun headers ()
  (format t "Content-type: text/plain; charset=\"UTF-8\"~2%"))

(headers)
(format t "~A č" (getenv "LANG"))
(exit)


But if I use this invocation, that it works:

#!/usr/bin/clisp -E utf-8
;; (setf custom:*default-file-encoding* "utf-8")
;; (setf custom:*misc-encoding* "utf-8")
;; (setf custom:*terminal-encoding* "utf-8")
;; (setf custom:*pathname-encoding* "utf-8")
;; (setf custom:*foreign-encoding* "utf-8")

(defun headers ()
  (format t "Content-type: text/plain; charset=\"UTF-8\"~2%"))

(headers)
(format t "~A č" (getenv "LANG"))
(exit)


and I am still concerned that I cannot set those
encodings within the script.
