Thanks for reaching out and we do apologize for any frustrations with unsupported characters. If you are still getting the error after using Notepad or TextEdit you'll need to re-type the text manually into the editor. We're sorry for any extra steps that are involved, however, copying text from another source can also copy problematic formatting or hidden code that doesn't work with our system. I will definitely submit your feedback to our programmers about this, and in the meantime please let us know if you need any further assistance.
