It might be right... remember, in UCS-2LE, each character is
represented with 16 bits, so 'e' would be (hex) 65 00, and that 00
would be seen by fprintf (which doesn't cope with UCS-2) as the end
of the string! But the output buffer would presumably hold 65 00 65
00 46 00 61 00 ....
Oh, hm.... This could also be a problem depending on how you're
going to use this function. Any of the krb5 library routines that
use "char *" for the password won't be able to properly determine the
length; you'd need to plug it in somewhere where a krb5_data object
is used to access the password, by pointer and length.
