Character classes
A character class is used to match a single character to a set of possible characters. A character class is denoted using square brackets ([ ]).
For example, a character class may contain each of the vowels:
'get' -match 'g[aeiou]t' 'got' -match 'g[aeiou]'
Within a character class, the special or reserved characters are as follows:
- -: Used to define a range
- \: Escape character
- ^: Negates the character class
