RFC 1557               Korean Character Encoding           December 1993


   The KSC 5601 [KSC5601] character set that includes Hangul, Hanja
   (Chinese ideographic characters), graphic and foreign characters,
   etc., is two bytes long for each character.

   For more information about Korean character sets please refer to the
   KSC 5601-1987 document.  Also, for more detailed information about
   the escape sequence and the shift function you can look for the ISO
   2022 [ISO2022] document.

Formal Syntax

   Where this document in its formal syntax does not agree with the
   description part, priority should be given to the formal syntax of
   the document.

   The notations used in this section of the document are according to
   those used in STD 11, RFC 822 [RFC 822] with the same meaning.

        * (asterisk) has the following meaning :
             l*m "anything"

   The above means that "anything" has to be used at least l times and
   at most m times.  Default values for l and m are 0 and infinitive,
   respectively.

   body            = *e-line *1( designator *( e-line / h-line ))

   designator      = ESC "$" ")" "C"

   e-line          = *text CRLF

   h-line          = *text 1*( segment *text ) CRLF




   segment         = SO 1*(one-of-94 one-of-94 SI

                                               ; ( Octal, Decimal.)

   ESC             =     ; ( 33, 27.)

   SO              =      ; ( 16, 14.)

   SI              =       ; ( 17, 15.)

   SP              =          ; ( 40, 32.)
