	It's been discussed, but not a lot of effort has gone into coming up  
with storage compatibility.

	It's pretty easy in my client to write a transcoder object to meet  
your exact requirements (basically assert the value to be a string,  
get the UTF-8 bytes from it and set the flags to whatever you want),  
but I wouldn't consider that a general long-term solution.
