The AlphaConfig interface extends the BaseValidatorConfig interface to provide additional configuration options specifically for validating alphabetic input. It allows you to tailor the validation behavior for alphabetic fields within your forms.

Defaults to false if not specified.locale (Optional): A string specifying the locale for character set validation. This can influence which characters are considered alphabetic based on regional variations (e.g., some languages might include accented characters).allowCharacters (Optional): A string containing additional characters that should be considered valid along with standard alphabetic characters (a-z and A-Z). This allows you to include special characters like hyphens (-) or underscores (_) as valid input if needed.
