OK. I'll implement the discussed customizations.

Now I get it, thanks for the explanation.

Sure, as long as it's not on by default. For example, add a new possible
value of `ruby-insert-encoding-magic-comment': `always'. Or `always-utf8'.

In this case, `ruby-mode-set-encoding' might short-circuit the whole
encoding detection logic and just always write `coding: utf-8'.
