React Javascript displaying/decoding unicode characters

Question

I have a string in unicode that i need to convert. I need to render the string with \u00f3 to ó. This is an example, it should happen with all other types of characters, á, í, ú...

I have the following basic code: https://jsfiddle.net/dddf7o70/

I need to convert

<Hello name="Informaci\u00f3n" /> 

into

Información 

Answer 1

Just pass it as a JS string:

<Hello name={'Informaci\u00f3n'} /> 

No need to do any manual processing (which is error prone).

Answer 2

If you have to work with strings that have, for whatever reason, literally those \u.... codes in them instead of being real letters, convert them to numbers, and then use String.fromCharCode() to turn those numbers into real letters. We can use a regexp replace with handler function for this:

function convertUnicode(input) {   return input.replace(/\\u[0-9a-fA-F]{4}/g,function(a,b) {     var charcode = parseInt(b,16);     return String.fromCharCode(charcode);   }); }  var Hello = React.createClass({   getInitialState: function() {     return {       name: convertUnicode(this.props.name)     };   },   render: function() {     return <div>Hello {this.state.name}</div>;   } });  React.render(   <Hello name="Informaci\u00f3n" />,   document.getElementById('container') );
