Re: Casting as wide a net as possible

[Random832]

I’ve been too clever for my own good. My “C1 controls” example
was not properly encoded as UTF-8, and I ignored the warnings
provided by Gnus for this situation. Below is, I hope, my
message as it was intended to appear (all properly encoded as
UTF-8).

P.S.  It may be instructive to note that my message was
apparently detected by Gnus as being in some kind of Japanese
encoding.
