                return false unless other
        end

        # The special value "*", if present in the Accept-Charset field,
        # matches every character set (including ISO-8859-1) which is not
        # mentioned elsewhere in the Accept-Charset field.
        return true if other.name.nil? || self.name.nil?

        # Same downcased names or different names for the same encoding should match
        return true if other.name.downcase == self.name.downcase ||
