유니코드의 인코딩

UTF-8

이와 관련한 내용은 UTF-8에서 볼 수 있습니다.

현재 가장 널리 쓰이는 인코딩 방식. 유니코드 범위에 따라 글자의 바이트 수도 달라진다. Basic Latin 영역의 문자는 1바이트로 인코딩을 해서 ASCII 체계와 완벽히 호환된다.

UTF-16

이와 관련한 내용은 UTF-16에서 볼 수 있습니다.

BMP에 할당된 문자는 2바이트로, 다른 문자는 4바이트로 처리되는 고정 바이트 형식 인코딩. 대표적인 사용 예로 NT 4.0 버전 이상의 Windows 운영 체제가 있다.

유니코드와 한글

유니코드에는 완성형 한글 자모조합 11,172자와 조합형 한글 낱자가 모두 수록되어 있다. 하지만 조합형은 데이터 크기가 커지기 때문에 옛한글 표기 등 특수한 목적을 위해서만 사용하고, 보통의 한글 인코딩에는 완성형을 사용한다.

본래 유니코드가 도입되기 전 대한민국에서는 KS X 1001 완성형 문자표에 기반한 EUC-KR 인코딩을 사용하였다. 그러나 이 문자표에 수록된 한글 자모조합은 2,350자에 불과하여 표준어조차 온전히 표기할 수 없었다. MS에서는 CP949(통합 완성형)이라는 코드로 한글의 나머지 글자들을 배열했지만 KS X 1001과 별개의 영역에 글자들을 우겨넣었기 때문에 코드가 다소 난잡했다.

한글은 유니코드 1.0 버전부터 지원하였다. 그러나 1.0때 KS X 1001의 2,350자, 1.1때 기타 4,306자를 추가해 6,656자밖에 표현이 불가능하였다. 이에 대한민국 대표는 유니코드 2.0 제정시 현대 한글 자모조합 11,172자를 다시 추가해줄 것을 요청하였고, 이에 2.0 버전에서 오늘날과 같은 완성형 자모조합이 코드표상에 제대로 배당되게 되었다.
