129 * Rules for HZ encoding
130 *
131 * In ASCII mode, a byte is interpreted as an ASCII character, unless a
132 * '~' is encountered. The character '~' is an escape character. By
133 * convention, it must be immediately followed ONLY by '~', '{' or '\n'
134 * (<LF>), with the following special meaning.
135
136 * 1. The escape sequence '~~' is interpreted as a '~'.
137 * 2. The escape-to-GB sequence '~{' switches the mode from ASCII to GB.
138 * 3. The escape sequence '~\n' is a line-continuation marker to be
139 * consumed with no output produced.
140 * In GB mode, characters are interpreted two bytes at a time as (pure)
141 * GB codes until the escape-from-GB code '~}' is read. This code
142 * switches the mode from GB back to ASCII. (Note that the escape-
143 * from-GB code '~}' ($7E7D) is outside the defined GB range.)
144 *
145 * Source: RFC 1842
146 *
147 * Note that the formal syntax in RFC 1842 is invalid. I assume that the
148 * intended definition of single-byte-segment is as follows (pedberg):
149 * single-byte-segment = single-byte-seq 1*single-byte-char
