131* Rules for HZ encoding
132*
133* In ASCII mode, a byte is interpreted as an ASCII character, unless a
134* '~' is encountered. The character '~' is an escape character. By
135* convention, it must be immediately followed ONLY by '~', '{' or '\n'
136* (<LF>), with the following special meaning.
137
138* 1. The escape sequence '~~' is interpreted as a '~'.
139* 2. The escape-to-GB sequence '~{' switches the mode from ASCII to GB.
140* 3. The escape sequence '~\n' is a line-continuation marker to be
141* consumed with no output produced.
142* In GB mode, characters are interpreted two bytes at a time as (pure)
143* GB codes until the escape-from-GB code '~}' is read. This code
144* switches the mode from GB back to ASCII. (Note that the escape-
145* from-GB code '~}' ($7E7D) is outside the defined GB range.)
146*
147* Source: RFC 1842
148*
149* Note that the formal syntax in RFC 1842 is invalid. I assume that the
150* intended definition of single-byte-segment is as follows (pedberg):
151* single-byte-segment = single-byte-seq 1*single-byte-char
