I was able to reproduce it but am a bit confused, since it doesn't
signal an error when message-body "æøå" is replaced by "abc", while
reusing the same cookie.
I tried to track it down with the following example. `cookie-val' is the
value of the cookie-string:
(string-bytes cookie-val)
=> 131
(string-bytes (encode-coding-string "æøå" 'utf-8))
=> 6
(string-bytes (concat (encode-coding-string "æøå" 'utf-8) cookie-val))
=> 143 ' why?
(string-bytes (concat (string-as-unibyte "abc") ans-cookie-val))
=> 134
Why does concat behave that strangely? What am I missing here? Is the
behavior of concatenating a unibyte and a multibyte string simply
undefined? But if so, shouldn't that be mentioned in the docstring? Or
is it a general rule that has to be followed, to not mix uni-/multibyte
in any function?
Please excuse me if that seems to be a silly question to you. I just
want to learn and understand how that really works behind the scenes.
Thanks for any help.
