<br>So, several questions re ISO 15924:<br>1) Is IPA Extensions range covered as a general rule in Latn? This wasn't<br>evident from <a href="http://www.unicode.org/iso15924/iso15924-codes.html" target="_blank">http://www.unicode.org/iso15924/iso15924-codes.html
</a> and other<br>pages I scanned on <a href="http://unicode.org" target="_blank">unicode.org</a>. In looking at some back correspondence on<br>ietf-languages it seems that it is.</blockquote><div><br>Yes.<br>Looking at <a href="http://unicode.org/cldr/utility/list-unicodeset.jsp?a=[:Block=IPA_Extensions:]">
http://unicode.org/cldr/utility/list-unicodeset.jsp?a=[:Block=IPA_Extensions:]</a>, you see 96 characters.<br>
<br>
If you subtract out all non-Latin characters, you get the same 96 characters.<br>

<br>2) Is there any precedent for specific characters or ranges in Unicode to be<br>covered by more than one ISO 15924 code? I believe I recall there are a few<br>cases, but that they are exceptions.</blockquote><div><br>
In Unicode, the association between script and character forms a complete partition. Each character has exactly one script. Any characters that are used in multiple scripts have the script value = common or inherited<br><br>
