character is a lead byte, the return value is nonzero.
If the
character is not a lead byte, the return value is zero. To get extended error

are unique to double-byte character sets. A lead byte introduces a double-byte
character. Lead bytes occupy a specific range of byte values. The IsDBCSLeadByte
function uses the ANSI code page to check lead-byte ranges.
