IMO, dig should only display what's actually in the DNS packets. Some  
other tool(s) can be used to render IDNs into whatever non-ASCII  
scripts/fonts may (or may not) be appropriate. The *last* thing dig  
needs are even more command line or environment variables.

The output you showed Ed illustrates the problem when poorly thought- 
out "features" are added and then break things when there was no need  
whatsoever for that behaviour.

I doubt the Linux kiddies will care. The message in Rob Pike's "cat -v  
harmful" USENIX talk from the late 1990s is just lost on them.
