Sorry, I was wrong about this and something I said earlier.

Even with the line present, I do not see the problem I thought
I saw earlier, of the *Warning* presenting only two encoding
options, one of which was raw text.  Dunno what build I saw
that in.

The screenshot I just sent is what I see even in the build
I reported about (and it mentions utf-8).  The rest of the
problems are as I reported them.
