Technically speaking, the content of the cookie value is opaque and can be anything the server wants, even binary data, as long as the resulting HTTP headers follow the rules of the HTTP specifications. By convention, most servers encode non-ASCII data, typically with URL-encoding (a non-ASCII byte is represented as "%XX", where XX is the hex value of the byte).

you can't transfer Unicode like that in headers, you might need to encode it into base64 or quoted-printable

I found out that Russian characters are not working as cookie values in iPhone browsers (Chrome, Safari), so I had to convert to base64. Although the same code worked well in desktop browsers without a need to convert to anything.
