<p style="margin-bottom:12.0pt"><span style="color:black">Hi,<o:p></o:p></span></p>
<p style="margin-bottom:12.0pt"><span style="color:black">I understand why people want these things, but it is not possible and will never be possible to treat label separators in quite the way people want. This is because the label separators don't actually
appear in the wire protocol, but the presentation format of domain names is also a kind of protocol.
<o:p></o:p></span></p>
<p style="margin-bottom:12.0pt"><span style="color:black">First, upper and lower case _are not_ equivalent in the DNS. The protocol makes them match, but the case is supposed to be preserved. You can observe this on the Internet.
<o:p></o:p></span></p>
<p style="margin-bottom:12.0pt"><span style="color:black">Second, mapping of actually different names (like the different spellings of China in Han characters) is quite different to the in-protocol match that the DNS unfortunately did for upper and lower case
ASCII. <o:p></o:p></span></p>
<p style="margin-bottom:12.0pt"><span style="color:black">But most importantly, in the wire format there is no separator character. Instead, the length of the label indicates the separation. But in zone files and the like, the separator is there for humans.
This is also part of the protocol, so we can't arbitrarily change it. Applications can map it, however. That is not quite the same but it is what idna does generally.
