HTML Validation Issue: Document uses the Unicode Private Use Area(s), which should not be used in publicly exchanged documents.

I want to use the character  as my submit character.   I am getting a validation warning:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Demo</title>
</head>
<body>

 <div>
  <input type="submit" class="fa submit" value="&#61442;">
 </div>

</body>
</html>

It is only a warning and not an error so you are good.

You could build a database of items like 1 = &#61442;, 2 = &#61443; etc. Then just post 1,2,3... and in your server side code, convert the 1 to &#61442 to display the content.  But like I said, it is just a warning.

This is  not based on HTML validation but rather a W3C Recommendation  Char Mod and the code you are using is Private Use.

You can ignore the warning or use an image but it may fail to validate under certain circumstances.

Randy, I think what you are saying is confusing but we said the same thing.

> This is  not based on HTML validation but rather a W3C Recommendation

And the validation from https://validator.w3.org/ which is based on the spec.  I'm not 100% sure but I think changing the doc type gets rid of the warning based on that spec.

In any case, the answer agreed is you can ignore.

Awarded points since this warning can be ignored.
