When using third-party programs such as Microsoft Word or Notepad, it is quite common for these programs to include hidden characters. If you copy and paste directly from this program into Zenu, these hidden characters can cause an "Invalid Character" error when you go to send your SMS/Text or email.
Identifying and Removing Invalid Characters
We recommend cleaning your description or text prior to pasting it in Zenu. Luckily, there are several free third-party websites that can be found by a simple Google search. Alternatively, you can run your text through a Unicode detector in order to locate and then remove the invalid characters.
