Char.IsSurrogatePair Method (String, Int32)
Indicates whether two adjacent Char objects at a specified position in a string form a surrogate pair.
Assembly: mscorlib (in mscorlib.dll)
Return ValueType: System.Boolean
true if the s parameter and the index parameter specify a pair of adjacent characters, and the numeric value of the character at position index ranges from U+D800 through U+DBFF, and the numeric value of the character at position index+1 ranges from U+DC00 through U+DFFF; otherwise, false.
Ordinarily, a single character is represented by a single UTF-16 code unit. UTF-16 encoding also supports surrogate pairs, which allow a single abstract character to be represented by two UTF-16 code units. The first code unit, whose value can range from U+D800 to U+DBFF, is the high surrogate. The second code unit, whose value can range from U+DC00 to U+DFFF, is the low surrogate. Individual surrogate code units have no interpretation of their own. For more information about surrogates and the Unicode Standard, see the Unicode home page.
