This says that the internal representation of the cookie-val string uses
up 131 bytes.

Note that `length' should return the same value, since the string
returned by encode-coding-string should be unibyte (i.e. is a sequence of
bytes, rather than sequence of characters).

Because the concatenation needs to convert the bytes held in the first
string into chars.  The internal representation of bytes >=128 as chars
takes up 2 bytes.
