How To Convert DOM Node Text Value To UTF-8 In JavaScript?

I need to send a text content of an HTML node over Ajax request, but first convert it to UTF-8. Is that possible? Thanks!

Solution 1:

function encode_utf8( s )
{
  return unescape( encodeURIComponent( s ) );
}

function decode_utf8( s )
{
  return decodeURIComponent( escape( s ) );
}

from http://ecmanaut.blogspot.com/2006/07/encoding-decoding-utf8-in-javascript.html

use it like this...

encode_utf8(document.getElementById(id).textContent);
