Be careful here, since Unicode strings will have every other byte as a zero.  I suspect with the above code sample you will truncate your string to either zero or one bytes, from the PCHAR point of view.  

There are C Run time routines to do these conversions.  Lookup converting Unicode to ASCII and converting ASCII to Unicode.

That's why I wrote

PWCHAR pw = pustr->Buffer;

A 'UNICODE_STRING' (like the NT Native API uses it) is

typedef struct _UNICODE_STRING {
    USHORT Length;
    USHORT MaximumLength;
#ifdef MIDL_PASS
    [size_is(MaximumLength / 2), length_is((Length) / 2) ] USHORT * Buffer;
#else // MIDL_PASS
    PWSTR  Buffer;
#endif // MIDL_PASS
} UNICODE_STRING;
