<p class="MsoPlainText">Hi, Karl<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Someone should have provided a response sooner.<o:p></o:p></p>

<p class="MsoPlainText">First, the re-ordering of data in ScriptExtensions.txt actually was done in Unicode 16.0. See
<a href="https://www.unicode.org/reports/tr44/tr44-34.html#Change_History">https://www.unicode.org/reports/tr44/tr44-34.html#Change_History</a>.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Regarding the entry for 02C7, the script extension was changed from {Common} in 15.1 (by virtue of no entry, hence defaulting to its Script property) to {Latin, Bopomofo} in 16.0. That was part of a set of additions to ScriptExtensions.txt
that UTC had approved at UTC #178 (January 2024) — see consensus 178-C39:<o:p></o:p></p>

<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The change was committed into the file within the following month, and would have been visible in public review no later than the Unicode 16.0 Beta.<o:p></o:p></p>

Subject: Changes to the Script Extension property in 16.0 that aren't documented in the release notes</span></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I got a complaint from the field that U+02C7 is unexpectedly listed as in the Latin script in 16.0<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Someone investigated and the only changes listed for that property are that the ScriptExtensions.txt file has been re-ordered.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I checked, and they are correct. I then looked at a difference listing between the 15.1 and 16.0 versions, and there are extensive changes beyond reordering.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Is there something we're missing, or did the 16.0 changes list omit these things?<o:p></o:p></p>
