IsSurrogatePair()
OutputVar := MfChar.IsSurrogatePair(highSurrogate, lowSurrogate)
OutputVar := MfChar.IsSurrogatePair(s, index)
Indicates whether the two specified MfChar objects form a surrogate pair.
Returns true if the CharCode value of the highSurrogate parameter ranges from 0xD800 through 0xDBFF, and the CharCode value of the lowSurrogate parameter ranges from 0xDC00 through 0xDFFF; Otherwise, false.
Indicates whether two adjacent characters in a string at a specified position form a surrogate pair.
Returns true if the s parameter includes adjacent characters at positions index and index + 1, and the numeric value of the character at position index ranges from 0xD800 through 0xDBFF, and the numeric value of the character at position index + 1 ranges from 0xDC00 through 0xDFFF; Otherwise false.
highSurrogate
The character instance of MfChar to evaluate as the high surrogate of a surrogate pair.
lowSurrogate
The character instance of MfChar to evaluate as the low surrogate of a surrogate pair.
s
A instance of MfString or a var containing string.
index
An instance of MfInteger or var containing integer that contains the starting position of the pair of characters to evaluate within s.
Throws MfInvalidOperationException if not called as a static method.
IsSurrogatePair(s, index) throws MfArgumentNullException if parameter s or index is null.
IsSurrogatePair(s, index) throws MfArgumentOutOfRangeException if index is less than zero or greater than the last position in s.
Throws MfNotSupportedException if Overloads can not match Parameters.
Throws MfInvalidOperationException if not called as a static method.
