The file.encoding seems to be Cp1252. :/

I'm not sure how the port is being opened because it seems to happen
automatically. Anything that makes it up to the top level (the
ultimate result of the base set of expressions) gets sent to the
client. I'm using Tomcat 6 with kawa-1.9.1.jar.

I set port-char-encoding at the very top of the example code I gave
before, right after:

;; -*- scheme -*-

and right before the first function definition (new code below).



I'll take a look at passing arguments to the Java process.

Thanks,

;; -*- scheme -*-

(set! port "UTF-8")
(set! port-char-encoding "UTF-8")

(define (bytes->string/utf-8 bytes)
  (<string> (<java.lang.String> bytes
                                0
                                bytes:length
                                "UTF-8")))

(let* ((data (string-append "<b>"
                            (bytes->string/utf-8 (<byte[]> 206 187))
                            "</b>")))
  (values-append (unescaped-data "<?xml version=\"1.0\" encoding=\"UTF-8\"?>")
                 data ", " (unescaped-data data)))
