Swift switch char{ case "\u{e2}:

Question

let splitLines = line.split(separator: "\u{e2}")

case "\u{e2}":
                print("FoundBadReturn")

let newText = text.replacingOccurrences(of: "\u{e2}", with: "\n")

I'm working with a RTF Document in UITextView. I'm trying to change Strings that contain \u{e2} char with \n None of these lines seem to work against Strings

Define doesn't work. Note that `\u{e2}` it is the same as `â` — Leo Dabus, Dec 23 '17 at 01:46
A String that has a "\u{e2}" does not split with the split function. — user8726606, Dec 23 '17 at 02:42
if char == "\u{e2}"{ newText.append("\n") } else { newText.append(char) } It don't work. — user8726606, Dec 23 '17 at 02:45
\u{e2} is a alternative of \n in a document that comes from word. — user8726606, Dec 23 '17 at 11:17
I first split the document on \n this gives me an array of lines. Unfortunately some of these lines have this char in them. I want to split the lines on that character. I've tried looping through the line testing for the character. Using the split function on the character. Using a switch/case test on the character and using the replacingOcurrances function on the character. None of these methods work. — user8726606, Dec 23 '17 at 11:23

The debugger print is misleading. The character is "\u{2028}" 'Line Separator' rather than "\u{e2}". The debugger does this because 0xE2 is the first byte of that character in UTF8, and it hides the rest. If you instead try to perform your operations (delete, replace, contains...) on "\u{2028}", they will work.

Have you tried the solution here? It works for me. https://stackoverflow.com/a/47835062/

phoneLabel.text?.replacingOccurrences(of: "\\p{Cf}", with: "", options: .regularExpression)

When copy phone number from `Phone` app, debuger show `\u{e2}`, but the real is: `\\p{Cf}` :)) – lee Jun 16 '20 at 07:01

I wrote the following function to solve this problem. It's probably not the best solution.

func splitOnAlternateNewline(line: String) -> [String]{
    var returnArray: [String] = []
    var aString = ""
    outLoop :for char in line{
        let aChar = String(char).utf16
        for a in aChar{
            if a == 8232{
                returnArray.append(aString)
                aString = ""
                continue outLoop

            }

        }
        aString.append(char)


    }
    returnArray.append(aString)
    return returnArray

}

8232 is indeed the decimal value of 0x2028. – entonio Sep 22 '18 at 18:36 — entonio, Sep 22 '18 at 18:36
