This constant returns a standard zero-width non-joiner character. You can use this constant as an alternative to the P constant. This character is invisible because it has a width of 0 pixels. Use this character if you don’t want to get rid of it at the end of string data processing. Useful to prevent data from being translated by function i(), by inserting dummy S character between the text that will go into function i().

In the example below, if $page->title value is “Windows”, the text below may be translated to “Jendela” by Language extension when your language preference is set to Indonesian. Whereas you don’t want it to be translated because you are referring “Windows” to the trademark of an operating system, not to the literal meaning of it.

<h2>
  <?= i($page->title); ?>
</h2>

To prevent the text from being translated by function i(), you can surround it with S constant. ¹

<h2>
  <?= i(S . $page->title . S); ?>
</h2>
