- SR-3448 Crash in String.replacingOccurrences(of:with:) with emoji on Linux
Issue Description:
When using String.replacingCharacters(in:with:) with emoji on Linux, I get a crash. This does not happen on macOS with the Xcode 8.2 Swift build.
This is likely related to https://bugs.swift.org/browse/SR-3448.
Sample code:
import Foundation
let str = "\u{1F468}\u{200D}\u{1F469}\u{200D}\u{1F467}\u{200D}\u{1F466} marcelo "
if let range = str.range(of: "ce") {
let updated = str.replacingCharacters(in: range, with: "")
print(updated)
