Yes.

Yes.

I don't like that idea much... a "badly configured device" today may be 
a "device with default config" tomorrow.

You say that escaping the string is not a valid solution, due to the DNS label 
size limit. But, how about this?:

if (the label is not a valid UTF8 string)
{
	escape the invalid characters
	if (new lenght of the DNS label < 255)
		Return the escaped label
	else
		Ignore this label, log a warning into syslog
}


This way, Avahi should work with *most* badly configured devices (as people 
don't usually use up 256 characters for a device name); and devices 
with "bad" names, that are too long to be sanitized, will be just ignored.


Just an idea...
