Symbolic Representation Of Return | \x0a Vs. Other

I'm trying to verify my code. Here is a regex check on it with out 0xa: As you can see at some places where there is a return character the regex does not match b.c. 0xa is used f

Solution 1:

I was surprised that it look like it groups the rows together, but it has to do with the star in your regexp. Change your regexp to [\x20-\x7e]+. Using the plus sign (one or more matches) instead of star (zero or more matches) I think you get the expected result.

If you want to see whats really is in the inputText-field on regexpal, open up the console in your browser and run document.getElementById('inputText').value.replace(/[^\x20-\x7e]/g,function(a){‌​a = a.charCodeAt(0).toString(16); return '\\u0000'.slice(0,6-a.length) + a;}); and you will get a true representation of the string.

Pretty print:

document.getElementById('inputText').value.replace(
  /[^\x20-\x7e]/g,
  function (a){‌
    ​a = a.charCodeAt(0).toString(16);
    return'\\u0000'.slice(0,6-a.length) + a;
  }
);
