    but i am unable to write a search function to auto replace every "" with ""

    Why not? What did you try?

      If you have a string, you can simply replace \ with \\

      @Pl45m4 how to replace it without seeking for each special char seperately?
      After compiled to string it is threated as single special char...
      Basically id like to show all info as raw text in text browser. Including \n \r etc but incoming data format is QString...

        Of course not.

        Regarding text.indexOf('\'); : you want to replace new-lines, right? So, it should be:

        text.indexOf('\n');
        

        To replace a simple

        someString.replace("\n", "\\n");

          @jsulm Not only new lines but all special chars..

          I guess 1 way is to loop trough text and use isNonCharacter() then add the extra "\"

            If you want to replace \ with \\
            text.replace ("\\", "\\\" );

                @Q139 One idea would be to take a look at qDebug() implementation as it does this at least for some special characters (like new lines).

                  @Q139 im afraid compiler removes 2 chars and replaces with 1 as there are not enough keys on keyboard for special chars.
