ZeroWidthWriter is a simple tool driven by a single file based on HTML. It is achieved by Javascript for backends and HTML for interface.
This is a simple tool which can write something implict string into a explict string. As a simple we can see here.
Encode: 'Hello' + 'World' -> 'Hello'
Decode: 'Hello' -> 'Hello' + 'World'
There is only a single file to use which is "index.html". You can open it with your browser (very pity for that IE not included)
After you open the html files in your browser, you can follow the tips in the html and get fun!
Just for fun!
