Got it. I knew ASCII characters were valid UTF-8 sequences so I'm not sure why that sentence tripped me up. It may be because I assumed the previous sentence, which requires UTF-8 encoding for non-ASCII characters, already disallowed non-UTF-8 encoded characters in host. Anyway, I just read too much into it.  Thanks for the clarification.

Hello Dave,

UTF-8 includes US-ASCII, so there should be no problem.
You say 'From the context, a "UTF-8 character sequence" seems to apply only to
non-ASCII characters.'. How did you come to that conclusion?

Regards,   Martin.
