       The input string must be enclosed in []'s, and the returned string is the expanded
       character set joined into a single string.
       The values enclosed in the []'s may be::
          a single character
          an escaped character with a leading backslash (such as \- or \])
          an escaped hex character with a leading '\0x' (\0x21, which is a '!' character)
          an escaped octal character with a leading '\0' (\041, which is a '!' character)
          a range of any of the above, separated by a dash ('a-z', etc.)
          any combination of the above ('aeiouy', 'a-zA-Z0-9_$', etc.)
