Which isn’t a huge surprise when you consider how tricky string containment is.</blockquote><div dir="auto"><br></div><div dir="auto">As someone who has used Swift professionally since it first came out, this subtle API change after import actually is a surprise to me.</div><div dir="auto"><br></div><div dir="auto">Would you be able to clarify where the line is between “tricky” and “not tricky” and if possible the reasoning behind making this distinction? Because as an outsider this seems to me like an unfortunate remnant of ObjC rather than an obvious and forward-thinking API decision.</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>

import Foundation<br>

let s = "Friedrichstra\u{df}e"<br>

In High/“Standard” German they’re not / would be pronounced differently etc. Some Germans call the “sharp s” an “sz” instead. So the difficulty of this distinction is not restricted to Unicode :)</div><div dir="auto"><br></div><div dir="auto">Cheers,</div><div dir="auto">Geordie</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
