결합 클래스란, 특정 문자가 다른 문자와 결합하여 하나의 문자를 형성할 때, 그 문자가 어떤 역할을 하는지에 대한 정보를 제공합니다. 예를 들어, 'a'와 'ˇ' (아카트)가 결합되어 'á'를 형성할 때, 'a'는 기본 문자로, ' '는 결합 클래스 230 (Combining Low Tone Mark)로, 결합 클래스 0 (Combining Spacing Accent)으로 반환됩니다.
IntlChar::getCombiningClass 함수의 반환 값은 0부터 255 사이의 정수입니다. 이 값은 Unicode Standard의 Combining Character Class에 따라 결정됩니다.

위의 설명을 바탕으로, IntlChar::getCombiningClass 함수의 반환 값은 특정 문자의 결합 클래스를 알려면, 문자의 Unicode 코드 포인트를 알아야 합니다. 그리고, 그 코드 포인트를 사용하여 결합 클래스를 조회하면 됩니다.
