Re: distinguishing between utf-8 and gb18030

I do not share your faith that both encodings won't be widely used, or that
they will converge to utf-8 within our lifetimes.

but if both encodings do appear without tagging, and the difference can
reliably be determined by heuristics, I do have faith that vendors will
implement those heuristics.
