We're wrapping CLR char arrays right now. But we're fully planning on going to bytes in the future once things settle down a bit. We're erring on the side of letting some things just work today vs. doing this correctly the first time and taking longer.

We should start with the char based version today with an eye of moving toward the byte-based version once we fix MutableString.

Thanks for the advice, Charlie!
