Jave - Remove carriage return + special characters from text

I am writing a code in java that takes text then remove all the Punctuations (, blanks - new line and numerals) all special character and just leave the A to Z letters. it works fine until gets to the first carriage return and stopped. I tried many version of replaceAll but it did not work, please help!

for example

IHN EMATMG EECNIWEA RSHI A RESOEF ES RLTCMEE-COEAACIROH TLNHR PIRMOA ECSHENEV CEDIAODED ULS NPHD TN EAE REIIY-MO TWL-EDTHTTEEN NTCIPRO TO TUERYMT MORCCIECLL,

then I get:

IHNEMATMGEECNIWEARSHIARESOEFESRLTCMEECOEAACIROHTLNHRPIRMOAECSHENEVCEDIAODEDULSNPHDTNEAEREIIYMOTWLEDTHTTEENNTCIPROTOTUERYMTMORCCIECLL

 package Cipher1;

import java.util.Scanner;

public class StripCipher
{
    public static void main(String[] args)
    {
        // Take the input of the encrypted text from the user.
        System.out.println(" Enter the cipher text : ");
        Scanner ScanText = new Scanner(System.in);
        String OriginalCipherText = ScanText.nextLine();

        // Eliminate the wide space and special characters present in the input
        // text.
        String CipherText = OriginalCipherText.replaceAll("\\s+", "");
        CipherText = OriginalCipherText.replaceAll("[^a-zA-Z]+", "");
        System.out.println(" Striped Cipher text is : " + CipherText);

        // Calculate the length of the text.
        int CipherTextLength = CipherText.length();
        System.out.println(" Lenght of the cipher text is : " + CipherTextLength);
    }
}

for clarifications I used the following but none of them work:

replaceAll("[\n\r]", ""); 
replaceAll("\\r|\\n", "")
replaceAll("[^\\w\\s]",""); 
replaceAll("[^\\p{L}\\p{Z}]","");

CipherText = OriginalCipherText.replaceAll("[^a-zA-Z]+", "");

No reason why that should not work. It can't contain carriage returns btw, since readLine will remove them

So looks like you are copying and pasting into your ScanText Scanner (which should be scanText btw for convention), which will not work for reasons the other experts mention.
