Special symbols in wysihtml5 editor

Question

I use wysihtml5 editor on my site and I would like to have the following functionality - if user inserts text with special characters they are transformed to html entities.

For example, user inserts:

"Sample text, sample text, sample text ©"

I need to transform it to:

"Sample text, sample text, sample text ©"

I didn't find any information related to special symbols in editor docs. One of the method I think about is to create listener for paste event and process special characters at this step.

Could you advice what is the best way to add this functionality to the editor?

Answer 1

you can use a RegExp character range to replace() them using a dynamic function:

strNew=strOld.replace(
  /([\u00A0-\u00FF])/g,  
  function(j,a){
             return "&#" + parseInt(a.charCodeAt(0), 16) + ";" ;
  }
);

this could be applied from the string you get back from your editor, or i guess, on the innerHTML of the editor's contenteditable tag.
