<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">So, in my view, nothing’s changed or broken WRT IDN’s use of normalization. Yes, another potentially confusing character combination now exists, but we already
have thousands of homographs. So I’m quite confused what the concern is since the mappings weren’t broken (at the logical level) and it’s only a homograph (which we already have to deal with).<o:p></o:p></span></p>

<p class="MsoNormal"><br>
To state it again, my concern -- my only concern -- is that this<br>
addition to Unicode appears to be a case where a precomposed<br>
character, which was previously possible to create (for some value of<br>
"possible" and "create") with a combining sequence, is added without<br>
NFC causing the new character and the previous combining sequence to<br>
match. That behaviour is surprising to me given what I understood at<br>
the time we worked on and published IDNA2008. (It is in fact<br>
surprising to me even now when I read the text of the standard, but I<br>
understand the argument that in fact the new character is somehow<br>
unrelated enough to the former combining sequence that the combining<br>
sequence never really worked, but that doesn't matter. I would<br>
probably find that argument more compelling if I understood why this<br>
case is different from ö in Swedish vs. ö in German, but never mind<br>
that, either.)<br>
