It doesn't quite follow the suggestion in the part about "so there's no
need to specify it explicitly in the file".  Isn't there a way other
than modifying the file to tell Texinfo that the encoding is utf-8?

By "Debian builds" I really meant "builds of Emacs made by the Debian
team", not "builds made under Debian".

I'd rather not try to be clever here.  E.g. your test will end up using
ASCII in non-English locales, even though they're just as likely to
properly handle those Unicode chars.  Just default to no.

Agreed.  One more thing: the config option might like to use a more
generic name like "--with-liberal-use-of-unicode".
