현재 위 코드를 이용하여 책을 쓰려고 하고 있습니다.

하지만, 한글을 넣을 때는 볼드체로 되지 않더라고요. (챕터, 섹션 이름을 넣을 때)

\bfseries\sffamily 부분이 글자체와 볼드를 결정해주는 것 같아서 이것저것 해보지만 잘 안됐습니다.

1. \textbf는 되지 않습니다.
2. \sffamily를 지우면 명조체가 되고 볼드가 됩니다. 하지만, 저는 산세리프체로 한글이 쓰이길 원합니다.

이 템플릿을 사용해서 쓰고 있습니다. (림크 청부가 안되네요..)

도와주시면 감사하겠습니다 ㅠ

*현재 한글을 kotex롤 넣어 쓰고 있습니다.
