Sounds like a question to ask of the IETF.

The DNS protocol is not 8-bit safe, much less any implementations of 
it.  This is because ASCII upper case characters are down cased in 
comparisons.  I.e., the following are equivalent label values in DNS: 
ABCDEF and abcdef and AbCdEf.  Each has distinct binary encodings, 
but DNS comparisons treat them as equal.
