[swift-users] Justification for Swift Design Decisions?

Specifically WRT to double quotes for characters, the Commonly Rejected Changes doc (https://github.com/apple/swift-evolution/blob/master/commonly_proposed.md) says, "Swift takes the approach of highly valuing Unicode. However, there are multiple concepts of a character that could make sense in Unicode, and none is so much more commonly used than the others that it makes sense to privilege them. We'd rather save single quoted literals for a greater purpose (e.g. non-escaped string literals)."

Otherwise, off the top of my head I'm not sure. If it's a particularly controversial decision, there's a fair chance it's come up on the swift-evolution list, though, so maybe search its archives?

Hope that helps,
