[dhi-servers] NameServer communication problems

Hi,

I will change the codes for the future - Victor has already modified  
his orb. I am worried about people who are looking at blank screens  
right now and won't know to update. The clients worked for more than  
a year with the UTF-8 encoding.

I thought that IRIS had hopes a number of Asian countries would  
establish data sharing with this technology. I would think that their  
OS's would be set up with something more modern than ASCII.

It would be great if you can register a UTF converter with the server.

Chuck
