No, that doesn't work, because the de-escaping on the backend side
happens *after* conversion to the backend encoding. If you insert escapes
into the middle of multibyte characters then you break the conversion.
Tatsuo's description of the problem is accurate (though I'm not sure
I agree with his solution ;-))
