Hi,

Do you have an example that I could work with ? ( e.g. the script that's causing this issue )

@MiyakeDev nice catch ! I sanitized the input when I first posted the script, but when I edited the post, the HTML entities were converted to characters. I made sure to fix it right away ! You can find the corrected script in the tutorial topic and below.
Code:
!window.fa_mentionner && !/\/privmsg|\/profile\?mode=editprofile&page_profil=signature/.test(window.location.href) && $(function(){$(function(){
  'SCEDITOR @HANDLE AUTO-SUGGEST';

  var container = $('.sceditor-container')[0],
