Remove \\U{E2} Characters from String

How to remove special character \u{e2} from string

Thank you every one for your help. You are so kind

I am able to find the invalid character using

phoneNumber?.map{$0.unicodeScalars.allSatisfy{$0.isASCII}}

and it returns

Optional<Array<Bool>>
  ▿ some : 12 elements
    - 0 : false
    - 1 : true
    - 2 : true
    - 3 : true
    - 4 : true
    - 5 : true
    - 6 : true
    - 7 : true
    - 8 : true
    - 9 : true
    - 10 : false
    - 11 : true

I am able to fix this issue using one line

phoneNumber?.filter{$0.unicodeScalars.allSatisfy{$0.isASCII}}

and Count is 10

using

phoneNumber?.filter{$0.unicodeScalars.allSatisfy{$0.isASCII}}.count

Hope it is helpful to others :)

To remove Unicode character from String in Java using REGEX

You can do this sequentially like below:

public static void main(final String args[]) {
    String comment = "Good morning! \u2028\u2028I am looking to purchase a new Honda car as I\u2019m outgrowing my current car. I currently drive a Hyundai Accent and I was looking for something a little bit larger and more comfortable like the Honda Civic. May I know if you have any of the models currently in stock? Thank you! Warm regards Sandra";

    // remove all non-ASCII characters
    comment = comment.replaceAll("[^\\x00-\\x7F]", "");

    // remove all the ASCII control characters
    comment = comment.replaceAll("[\\p{Cntrl}&&[^\r\n\t]]", "");

    // removes non-printable characters from Unicode
    comment = comment.replaceAll("\\p{C}", "");
    System.out.println(comment);
}

Remove unwanted unicode characters from string

testString = Regex.Replace(testString, @"[\u0000-\u0008\u000A-\u001F\u0100-\uFFFF]", "");

or

Eliminating Unicode Characters and Escape Characters from String

Try

String  stg = "\u2029My Actual String\u2029 \nMy Actual String";
Pattern pat = Pattern.compile("(?!(\\\\(u|U)\\w{4}|\\s))(\\w)+");
Matcher mat = pat.matcher(stg);
String out  =  "";
while(mat.find()){
    out+=mat.group()+" ";   
}
System.out.println(out);

The regex matches all things except unicode and escape characters. The regex pictorially represented as:

Output:

My Actual String My Actual String
