o […]-- Matches any single character specified within the brackets. The closing bracket is treated as a
member of the character class if it immediately follows the opening bracket (i.e. "[]]" matches a single closed
bracket). Within this class, "-" can be used to specify a range unless it is the first or last character (e.g. "[A-
Cf-h"] is equivalent to "[ABCfgh]"). A character class may be negated by specifying "^" as the first character.
To match a literal of this character, place it elsewhere in the class.
Note: The special characters "?", "*", and "[" lose their function if preceded by a single "\", and a single "\" can
be matched using "\\".
