Description
Indicates the kind of byte that occupies specified position in UnicodeString.
ByteType indicates what kind of byte exists at the byte indicated by index (counting from 1) in the UnicodeString. Note that index is an element index into the string, not a character or byte index. The following table lists 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.
