- Vis displays the contents of the specified files, or of standard input
- if no files are specified or when the special filename "-" is
- encountered. Non-printable characters are made visible by displaying
- them in the following format. For characters with a value of greater
- than 127 (i.e. the high bit is set; these are known as metacharacters),
- the string "M-" is displayed followed by the character with a value of
- 128 less (i.e. with the high bit reset). For characters with values of
- less than 32 (control characters), except for newline and tab (see
- below), the character '^' is displayed followed by the character with a
- value of 64 more (i.e. '@' or a capital letter). The DEL character
- (value of 127) is displayed as "^?". For characters in the range
- 128-157 (control characters with the high bit set), both "M-" and "^"
- will be displayed.
