The character group tokenizer accepts the following parameters:

1. `tokenize_on_chars`: Specifies a set of characters on which the text should be tokenized. The tokenizer creates a new token upon encountering any character from the specified set, for example, single characters `(e.g., -, @)` and character classes such as `whitespace`, `letter`, `digit`, `punctuation`, and `symbol`.
