I would like to replace the search submit button with a Font Awesome character like the Magnifier (Search Icon) character, and put Search the site inside the search box.

How can I achieve this?

Instructions for Drupal 8 / FontAwesome 5

Create a YOUR_THEME_NAME_HERE.THEME file and place it in your themes directory (ie. your_site_name/themes/your_theme_name)

Paste this into the file, it is PHP code to find the Search Block and change the value to the UNICODE for the FontAwesome icon. You can find other characters at this link https://fontawesome.com/cheatsheet.

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
}
?>

Open the CSS file of your theme (ie. your_site_name/themes/your_theme_name/css/styles.css) and then paste this in which will change all input submit text to FontAwesome. Not sure if this will work if you also want to add text in the input button though for just an icon it is fine.

Make sure you import FontAwesome, add this at the top of the CSS file. Font Awesome 4 has different code (ie. font-family: FontAwesome;)

@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

then add this in the CSS

input#edit-submit {
	font-family: 'Font Awesome\ 5 Free';
	background-color: transparent;
	border: 0;  
}

FLUSH ALL CACHES AND IT SHOULD WORK FINE

Add Google Font Effects

If you are using Google Web Fonts as well you can add also add effects to the icon (see more here https://developers.google.com/fonts/docs/getting_started#enabling_font_e...). You need to import a Google Web Font including the effect(s) you would like to use first in the CSS so it will be

@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,800&effect=3d-float');
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

Then go back to your .THEME file and add the class for the 3D Float Effect so the code will now add a class to the input. There are different effects available. So just choose the effect you like, change the CSS for the font import and the change the value FONT-EFFECT-3D-FLOAT int the code below to font-effect-WHATEVER_EFFECT_HERE. Note effects are still in Beta and don't work in all browsers so read here before you try it https://developers.google.com/fonts/docs/getting_started#enabling_font_e...

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
  $form['actions']['submit']['#attributes']['class'][] = 'font-effect-3d-float';
}
?>

For Drupal 8 / FontAwesome 5 

If you have the fontawesome module already installed you can add to your THEMENAME.theme file

use Drupal\Component\Render\FormattableMarkup;

function THEMENAME_form_search_block_form_alter(&$form, &$form_state) {
    $form['keys']['#attributes']['placeholder'][] = t('Search');
    $value = new FormattableMarkup('<i class="fas fa-search"></i>@text', ['@text' => '',]);
    $form['actions']['submit']['#value'] = $value;
}

Hi, as the title says, I tried your snippet with no luck

$value = new FormattableMarkup('<i class="fas fa-search"></i>@text', ['@text' => '',]);
        $form['actions']['submit']['#value'] = $value;

removes the existing value, but the value remains empty.
