Maciej did have an objection to doing this in a simplistic way (always using UTF-8). He wrote:

If someone can find a way to do use a more compact encoding “opportunistically”, but still allow any arbitrary 16-bit value for any character, I’m open to that. If not, please note that Maciej’s objection is one that I share.
