설명

유니코드 표준은 서로게이트 쌍을 두 코드 단위의 시퀀스로 구성 된 단일 추상 문자에 대 한 코딩 된 문자 표현으로 정의 합니다. 여기서 쌍의 첫 번째 단위는 상위 서로게이트이 고 두 번째는 하위 서로게이트입니다.The Unicode Standard defines a surrogate pair as a coded character representation for a single abstract character that consists of a sequence of two code units, where the first unit of the pair is a high surrogate and the second is a low surrogate. High surrogate u+d800부터 U + DBFF 까지의 범위에 유니코드 코드 포인트를 이며 하위 서로게이트 u+dc00부터 U + DFFF 까지의 범위에는 유니코드 코드 포인트입니다.A high surrogate is a Unicode code point in the range U+D800 through U+DBFF and a low surrogate is a Unicode code point in the range U+DC00 through U+DFFF.

제어 문자는 유니코드 값 인 U + 007F 또는 u+0000에서 U + 001F 또는 u+0080 ~ U + 009f 까지의 범위에는 문자입니다.A control character is a character for which the Unicode value is U+007F or in the range U+0000 through U+001F or U+0080 through U+009F.

.NET의 문자 소 즉, 단일 문자로 표시 되는 텍스트 단위로 텍스트 요소를 정의 합니다..NET defines a text element as a unit of text that is displayed as a single character, that is, a grapheme. 텍스트 요소는 기본 문자, 서로게이트 쌍 또는 결합 문자 시퀀스입니다.A text element can be a base character, a surrogate pair, or a combining character sequence. 유니코드 표준은 조합 문자 시퀀스를 기본 문자와 하나 이상의 조합 문자 조합으로 정의 합니다.The Unicode Standard defines a combining character sequence as a combination of a base character and one or more combining characters. 기본 문자 또는 조합 문자에 서로게이트 쌍을 나타낼 수 있습니다.A surrogate pair can represent a base character or a combining character.

조합 문자 시퀀스 올바르지 않으면 해당 시퀀스의 모든 조합 문자도 반환 됩니다.If a combining character sequence is invalid, every combining character in that sequence is also returned.

결과 배열의 각 인덱스는 시작 텍스트 요소 인덱스, 기본 문자 또는 high surrogate입니다.Each index in the resulting array is the beginning of a text element, that is, the index of the base character or the high surrogate.

각 요소의 길이 쉽게 연속 인덱스 간의 차이 따라 계산 됩니다.The length of each element is easily computed as the difference between successive indexes. 배열의 길이 보다 작거나 문자열의 길이 같고은 항상입니다.The length of the array will always be less than or equal to the length of the string. 이 메서드는 인덱스 0, 2 및 4를 반환 하는 예를 들어 "\u4f00\u302a\ud800\udc00\u4f01" 문자열을 지정 합니다.For example, given the string "\u4f00\u302a\ud800\udc00\u4f01", this method returns the indexes 0, 2, and 4.
