Hi, Willem!
Glad to hear, that you solved this.
By the way, I think it is not Tomcat, but the browser that is confused when the
encoding is not specified in the Content-Type header.
Those question marks were '? in a romb' i.e. Unicode replacement symbol. I.e.
as if those were replaced at the browser side. When PrintWriter replaces
symbols, it prints '?' punctuation mark.
Is it true, that the Content-Type header of your Ajax responses now has
the ";charset=..." suffix? (Is Content-Type updated from your
setCharacterEncoding(), or not?)
Also, I have heard that Ajax responses that are read through XmlHttpRequest
are expected to be in UTF-8. E.g., mentioned here:
http://dojotoolkit.org/book/dojo-book-0-9/part-3-programmatic-dijit-and-dojo/i18n/encoding-considerations
Also, your HTML pages do not specify their charset explicitly, thus the
browser has to autodetect their encoding,
http://www.w3.org/TR/html4/charset.html#spec-char-encoding
Also, Tomcat wiki:
http://wiki.apache.org/tomcat/FAQ/CharacterEncoding
