Just because it is more convenient and it is what is expected many cases
where strings are used (email address, hostnames, ip address...).
The string could be checked by the serializer to ensure that it does not
contain non-ASCII chars, in wich case a contextual string serializer can be
used instead (on a per page basis for example)

So what is the correct thing to do?

BTW, this patch should allow deferred response from callRemote, but I does
not seem to work. I don't understand why.
