    Amend bc73a85778ffb1432bdc510d9a710e7394f42163
    
    Missing return in `specialCharKindToXMLEntity`. Previously, the
    functions that were merged into `specialCharKindToXMLEntity` did not
    return any kind of error in case an unknown special character is met
    (enumerated value). This behaviour is preserved.
