Description

Use LeadBytes to test whether a value can represent the lead byte in a double byte character. If an individual value is in the LeadBytes set, it is not necessarily used as the lead byte of a double byte character. It may also appear as the second byte of a double byte character. To determine whether the character is used as a lead byte, use the global ByteType or StrByteType function.

Note: LeadBytes is always empty when running on a system with a locale that does not use a multi byte character system (MBCS).
