This is not a support forum for Copy & Pray.

Have you even read this?

In which environment?  See my update.

Hardly:

That is a Web application.  If you are asking here, you are asking to do it 
in your own code instead.

So that is _not_ what I said.

Because of the limitations of Base64, they are basically using the same 
workaround as I did in my update.  For example,

  ć

is encoded as

  xIc=

as it is with

| > window.btoa(encodeURIComponent("ć").replace(/%([0-9A-F]{2})/g, (m, code) 
|   => String.fromCharCode(parseInt(code, 16))))
| "xIc="

(Our inputs and outputs match; their code is minified, so I will not bother 
to check further.)
