IsHighSurrogate()
OutputVar := MfChar.IsHighSurrogate(c)
OutputVar := MfChar.IsHighSurrogate(s, index)
Indicates whether the specified character of c is a high surrogate.
Returns true if c is high surrogate; Otherwise, false.
Indicates whether the specified character is a high surrogate that ranges from U+D800 through U+DBFF for the character at position index in s.
Returns true if the character at position index in s is high surrogate that ranges from U+D800 through U+DBFF; Otherwise, false.
c
The character to evaluate. Can be a var containing character or MfChar instance or string var containing hex value Eg:"0x0061". c corresponds to a single linguistic Unicode character.
s
A string. Can be a string var or MfString instance.
index
The zero-based index position of the character to evaluate in s. Can be a Integer var or MfInteger instance.
Throws MfInvalidOperationException if not called as a static method.
Throws MfArgumentOutOfRangeException if index is not in the valid range of s.
Throws MfNotSupportedException if call to method is outside its overloads.
Throws MfInvalidOperationException if not called as a static method.
Static Method.
In addition to representing single characters using a 16-bit code point, UTF-16 encoding allows abstract characters to be represented using two 16-bit code points, which is known as a surrogate pair. The first element in this pair is the high surrogate. Its code point can range from U+D800 to U+DBFF. An individual surrogate has no interpretation of its own; it is meaningful only when used as part of a surrogate pair.
