javascript - Is it possible to convert a font icon back into it's private use code? -

for example, using fontawesome, , have span contains icon:

written in html:

<span class="icon">&#xf05a;</span>

though once rendered on page:

<span class="icon"></span>

is there way retrieve special character code f05a once has been rendered?

i.e.

var code = $('.icon').html(), privateusecode;  console.log(code); //   ?????  privateusecode = '\f05a'; // or similar

much appreciated!

var privateusecode = $('.icon').text().charcodeat(0);

hopefully html represented, because whitespace screws up
