UnicodeString::ByteType Method

Indicates the kind of byte that occupies specified position in System::UnicodeString.

Pascal

function ByteType(index: Integer): TStringLeadCharType;

C++

__fastcall TStringLeadCharType ByteType(int index) const;

Description

System::UnicodeString::ByteType indicates what kind of byte exists at the byte indicated by index (counting from 1) in the System::UnicodeString. Note that index is an element index into the string, not a character or byte index. These are the possible return values.

Constant	Meaning
ctNotLeadChar	Not a lead character.
ctbLeadSurrogate	Lead surrogate pair character.
ctTrailSurrogate	Trailing surrogate pair character.

Note: No checking is done to ensure that index is less than the length of the string. It is the caller's responsibility to ensure that Index is not out of bounds.
