This module contains a number of classes that represent special characters.
Each token represents one and only one character. It is recommended that you
make use of these classes instead of providing their corresponding characters
as strings on your own in order to prevent any errors that relate to character
escaping from happening.
Classes & methods

Below are listed all classes within :py:mod:`pregex.core.tokens`
along with any possible methods they may possess.
