Ah! Forgot about NSData. But all I saw was it likely coming out of NSTextStorage meaning an NSAttributedString. I wasn't seeing that going *reliably* into unsigned char []  buffer.
I would think it safer to ensure encoding things were covered.

I May have read more into it than is there, but I was thinking it as not necessarily enough space for what may be in the backing store of the textView. Probably in that I'm always working with things where I do have to remind people that everything isn't in ASCII.

I've been up too long with not enough sleep...
