Hmm yes, it's the bug 7222. I quickly looked at the response.scm
source. I think the content-length of the response have been computed
badly around line 147.

...
(apply + (map
           (lambda (c)
              (if (string? c)
                  (string-length c)   ;; here it is
                  (bytes-length c)))
           (cdr resp)))
...

Here is a demonstration of the situation;

> (string-length "şişko")
5
> (bytes-length (string->bytes/locale "şişko"))
7

I tried to convert the string to bytes before deciding it's length
(using something like the demo above) but I got this error:

compile: variable not provided (directly or indirectly and at the expected position) from module: |,/usr/local/plt/lib/plt/collects/web-server/response| in: provide/contract-contract-id-TEXT/HTML-MIME-TYPE.11
