<div dir="ltr">Is this really correct? Character and UnicodeScalar are not synonyms. The Character type represents a character made up of one or more Unicode scalars (i.e. an extended grapheme cluster). Is a CharacterSet a set of Unicode-compliant characters that happens to be restricted to those characters each made up of only a single Unicode scalar, or is it meant to be a set of Unicode scalars? My read of the Foundation documentation is that it is the former.<div class="gmail_extra"><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Sep 28, 2016 at 4:27 PM, Erica Sadun via swift-evolution <span dir="ltr"><<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><div>Chris: "<span style="font-family:Palatino-Roman"><i>Also, it is worth saying that any source breaking change still has to have an </i></span></div><div><span style="font-family:Palatino-Roman"><i>ultra-compelling reason to be worth considering.
