- SR-1204 Truncated result of stringByAddingPercentEncodingWithAllowedCharacters
Issue Description:
Foundation methods .removingPercentEncoding and .addingPercentEncoding on Linux(Ubuntu) do not work the same as they do on MacOS, when using non latin unicode symbols.
Example code for .removingPercentEncoding:
import Foundation
let cyrillicString = "\u{0434}\u{043E}\u{043C}"
//returns "дом"
let cyrillicEscapedString = cyrillicString.removingPercentEncoding
//returns "д\u{ef}" on Linux. On MacOS returns "дом" i.e. same string which is expected
let chineseString = "\u{623F}\u{5B50}"
//returns "房子"
let chineseEscapedString = chineseString.removingPercentEncoding
//returns "\u{ef}" on Linux. For MacOS result is same as chineseString
let arabicString = "\u{0645}\u{0646}\u{0632}\u{0644}"
//returns "منزل"
let arabicEscapedString = arabicString.removingPercentEncoding
//return "من" on Linux
let randomString = "\u{00E0}\u{00E6}"
//returns "àæ"
let randomEscapedString = randomString.removingPercentEncoding
//returns "à" on Linux
let latinString = "home"
//returns "home"
let latinEscapedString = latinString.removingPercentEncoding
//returns "home"
Example code for . addingPercentEncoding:
import Foundation
let string = "\u{0434}\u{043E}\u{043C}"//returns "дом"
let escaped = string.addingPercentEncoding(withAllowedCharacters: .alphanumerics)
//returns "%D0%B4%D0", while it should return "%D0%B4%D0%BE%D0%BC"
