Right behavior of -x option?

[Roman Rakus]

In RH bugzilla we have open bug impeaching right behavior of -x option.
Reporter is using japanese environment and is trying:

bash -x -c "echo \"あいうえお\""

echoing any japanese sentence.

and bash write out:
+ echo $'\343\201\202\343\201\204\343\201\206\343\201\210\343\201\212'
sentence in octal digits.

He is arguing that -x turn on debugmode and wants to see readable japanese 
sentence.

My opinion is that -x isn't debugmode and this is right behavior. I think there 
must be any reason why the echo is called with octal digits, but I really don't 
know why?
Maybe it's something in readline...
