[:character_class:] represents a character class that matches all characters belonging to that class
[=character_class=] represents an equivalence class.
It matches all characters with the same collation value, including itself.
For example, if o and (+) are the members of an equivalence class, then =o=, =(+)=, and [o(+)] are all synonymous.
An equivalence class may not be used as an endpoint of a range.
The following table lists the standard class names.
alnum Alphanumeric characters alpha Alphabetic characters blank Whitespace characters cntrl Control characters digit Digit characters graph Graphic characters lower Lowercase alphabetic characters print Graphic or space characters punct Punctuation characters space Space, tab, newline, and carriage return upper Uppercase alphabetic characters xdigit Hexadecimal digit characters
