IETF draft released - Related Issues.

I found the following in this link provided by Zfreud which appears to raise some profound issues. It would suggest that more characters may be banned including Dingbats and the notorious Hyphen.

http://www.ietf.org/internet-drafts/...xtsteps-05.txt

<<<4.1.1. Elimination of all non-language characters

Unicode characters that are not needed to write words or numbers in
any of the world's languages should be eliminated from the list of
characters that are appropriate in DNS labels. In addition to such
characters as those used for box-drawing and sentence punctuation,
this should exclude punctuation for word structure and other
delimiters: while DNS labels may conveniently be used to express
words in many circumstances, the goal is not to express words (or
sentences or phrases), but to permit the creation of unambiguous
labels with good mnemonic value.

4.1.2. Elimination of word-separation punctuation

The inclusion of the hyphen in the original hostname rules is a
historical artifact from an older, flat, name space. The community
should consider whether it is appropriate to treat it as a simple
legacy property of ASCII names and not attempt to generalize it to
other scripts. We might, for example, not permit claimed equivalents
to the hyphen from other scripts to be used in IDNs. We might even
consider banning use of the hyphen itself in non-ASCII strings or,
less restrictively, strings that contained non-Roman characters.>>>
