Excuse me?  That sounds like a complete cop-out, to me.

But if you're fine with pasted text from manuals not being
readable, who am I to say that this is a problem?

Telling users to avoid non-ASCII characters flies in the
face of spreading non-ASCII characters all over the manuals.

Do you honestly expect users to strip out all of the curly
quotes or replace them all with ASCII quotes, just to be
able to cite text in the manuals?
