charlist is a group of one or more characters enclosed in brackets ([]) and can be used to match any single character in a string. It may include any of the following characters:

•	Almost any character in the ANSI character set including digits

•

The special characters opening bracket ([), question mark (?), number sign (#) and asterisk (*) can be used for matching only if enclosed in brackets. The closing bracket (]) can't be used within a charlist to match itself, but it can be used outside the group as an individual character. A hyphen (-) can be used at the beginning or end of charlist to match itself. In any other position it indicates a range of characters.

•

A range of characters can be specified by placing a hyphen between lower and upper bounds. For example, [a-z], [A-Z] or [0-9]. Multiple ranges can be specified without any delimiter. For example [a-zA-Z0-9] matches any alphanumeric character. When a range of characters is specified they must appear in ascending sort order. [A-Z] is valid, but[Z-A] is not.
