Thus, represents .strn "!;" . +Note: strings in \*(TX consist of Unicode code points, not UTF-8 bytes; +therefore the elements of a string literal notation cannot specify individual +bytes. Each instance of hexadecimal or octal escape specifies a code point, +even if its value lies in the 8 bit range. +However, when a \*(TX string is encoded to UTF-8, +every code point in the range U+DC00 through U+DCFF is converted to a +a single byte, by taking the low-order eight bits of its value. By manipulating +code points in this special range, \*(TX programs can output arbitrary binary +data into text streams.

More detailed information is given in the section +Character Handling and International Characters. + If the line ends in the middle of a literal, it is an error, unless the last character is a backslash. This backslash is a special escape which does not denote a character; rather, it indicates that the string literal continues |
