title: tinymce convert bbcode to html code
body: <p>I want that my tinymce convert the bbcode to html code. I am adding tinymce in Extjs 6. When I want to make the Bold, it writes me in the html code [b] and it is the same thing for: italic, underlined, size.
  I follow this link but it's  not working too: <a href="https://stackoverflow.com/questions/9210680/convert-bbcode-to-html-using-javascript-jquery">Convert BBcode to HTML using JavaScript/jQuery</a>
  How can change that please, because it is showing on my website like this: 
  [b]Test[/b] instead of <strong>Test</strong>
  This my code:</p>
