At the DHCP Leases page, many hostnames are empty.

In the DHCP logs, often I see "Hostname Unsuitable for Printing".

I am guessing this is because of extended ascii characters. Would it be possible to either handle the extended ascii range (with utf-8 perhaps), or to replace those unsuitable chars with "?", rather than just showing nothing.

It could be just 1 or 2 letters which are unsuitable, and the rest of the hostname might be useful. Another idea might be to "romanise" the characters.. So if the hostname was "ápple", convert this to "apple"
