Guide to defining the encoding of an XML file with JavaScript

Hi there, I am currently facing an issue with encoding while creating a document using JavaScript. The problem is that the document rejects all non-ascii characters. For example, when passing the string "verificación", it gets replaced by "". Any suggestions on how to fix this?

Below is the code snippet causing the issue:

function createDoc(string){
    if (window.DOMParser)
      {
        parser = new DOMParser();
        
        doc = parser.parseFromString('<?xml version="1.0" encoding="UTF-8"?>'+string, "text/xml");
      }
    else // Internet Explorer
      {
        doc = new ActiveXObject("Microsoft.XMLDOM");
        doc.async = "false";
        doc.loadXML('<?xml version="1.0" encoding="UTF-8"?>'+string);
      }

    return doc
}

Thank you in advance for any assistance provided.

Answer №1

It's worth noting that JavaScript strings are encoded in UTF-16, so specifying this may help.

Before parsing the string, consider its origin. Is the string accurate and valid at that point?

Considerations should also be made around when and where the string is displayed, taking into account the expected encoding method.
