It looks as if it's a zero-padded string; that will happen to work currently, as string values are null-terminated and 
if there are any padding bytes, the first of them will terminate the string.

We might want to have an FT_STRINGZPAD type, to make it clear that some fields are zero-padded rather than counted or 
null-terminated.
