+/**************************************HZ Encoding*************************************************
+* Rules for HZ encoding
+* 
+*   In ASCII mode, a byte is interpreted as an ASCII character, unless a
+*   '~' is encountered. The character '~' is an escape character. By
+*   convention, it must be immediately followed ONLY by '~', '{' or '\n'
+*   (<LF>), with the following special meaning.
+
+*   1. The escape sequence '~~' is interpreted as a '~'.
+*   2. The escape-to-GB sequence '~{' switches the mode from ASCII to GB.
+*   3. The escape sequence '~\n' is a line-continuation marker to be
+*     consumed with no output produced.
+*   In GB mode, characters are interpreted two bytes at a time as (pure)
+*   GB codes until the escape-from-GB code '~}' is read. This code
+*   switches the mode from GB back to ASCII.  (Note that the escape-
+*   from-GB code '~}' ($7E7D) is outside the defined GB range.)
+*
+*   Source: RFC 1842
+*
+*   Note that the formal syntax in RFC 1842 is invalid. I assume that the
+*   intended definition of single-byte-segment is as follows (pedberg):
+*   single-byte-segment = single-byte-seq 1*single-byte-char
