No, it's not.

Yes it does. To me, this approach felt "hackish" so I didn't come up with a patch :) But I still don't have better idea how to fix it so it'll have to stay like this.

It would probably be correct to use:

if $encoding == "UTF-8"
	scan(/./u).size
else
	length
end

Thats because scan returns a array (hence using the size), without scan you are just invoking on string and it's correct to use length (for some reason size works too, backward compatibility?)
