I'm using Japanese and haven't had any problem with submitting incidents. Please paste the special character that needs to be included in an incident.

>4) I need the special characters to be encoded. How to do it

Encoded to what? There are several encoding schemes. Which one is needed?

ServiceNow saves string in UTF-8 and I haven't had problem with it.

Please provide a concrete example of text to be entered into an incident.

Not sure what's the purpose of converting string to hex.

Following code will convert a string to hex.

function toHex(str) {
  var result = '';
  for (var i=0; i<str.length; i++) {
    result += str.charCodeAt(i).toString(16);
  }
  return result;
}

ServiceNow also has a base64 encoder.

var str = "<string to encode>";
var res = GlideStringUtil.base64Encode(str);
