As an additional interesting point here, we could in general normalize unicode strings. This could potentially reduce the size of unicode characters or allow us to constant propagate certain unicode algorithms in the optimizer. > > -Joe > _______________________________________________ > swift-evolution mailing list > [email protected] > https://lists.swift.org/mailman/listinfo/swift-evolution _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
